Description Luciano Montanaro 2005-11-16 10:50:00 UTC
Version:           3.5rc1 (using KDE KDE 3.5.0)
Installed from:    SuSE RPMs

Akregator cannot be started for me since I upgraded to RC1.
Beta2 was ok.
starting akregator from the command line, I get the following message:
akregator: ERROR: Communication problem with akregator, it probably crashed.

The crash window does not appear, however, strace output suggests akregator actually crashes.

I see also this line:

*** glibc detected *** malloc(): memory corruption: 0x08393f88 ***
I'll attach the strace output.

Have you upgraded to 3.5.0? Does Akregator work now for you?

Backtrace produced by KDE crash handler

Akregator crashes on startup saying "Communication problem with akregator, it
probably crashed." This problem started when I upgraded to KDE 3.5.0 and also
upgraded akregator with packages obtained from
http://pkg-kde.alioth.debian.org.

Comment 7 Frank Osterfeld 2006-02-13 15:46:22 UTC
It seems that Akregator crashes while accessing the backend corrupt the metakit storage, which causes crashes then at startup.
A workaround is to move ~/.kde/share/apps/akregator/Archive/*mk4 somewhere else. That should make Akregator start again, but all archived articles are lost.You can then copy mk4 files back and test which one causes the crash...

It would be _very_ useful if someone experiencing this crash could zip the files in Archive/ and send them to me (frank.osterfeld at gmail.com) and also his feeds.opml. (If you want to help even more, identify the exact archive file that causes the crash).
Comment 8 Frank Osterfeld 2006-02-25 15:45:04 UTC
SVN commit 513455 by osterfeld:

Lock archive to avoid metakit archive corruption due to multiple write access.
Usually Akregator being a KUniqueApplication avoids multiple Akregator instances accessing the archive, but there seem to
be some cases where KUniqueApp is not safe enough (right after update, multiple KDE sessions, when using --nofork option).
So we lock the archive like KMail does: if locking fails, show an error message to the user, giving him the possibility to 
either continue without archive, or to force access.
As this is a severe bug (multiple write access can corrupt archives, which can make Akregator crash at startup), I think 
making use of the message unfreeze is justified.

Comment 17 Vincent Panel 2006-07-07 12:47:16 UTC
Hi !

I got a problem starting akregator after a machine crash. It's due to a corrupted archive file because moving my archive folder solved the startup issue. But I'm a bit puzzled : how can I identify which mk4 is causing the crash ? It looks like moving some mk4 files out of the Archive folder is making Akregator hang (not crash).

Thus a little feature request : could it be possible to display on output (when launching from the command line) which mk4 file is being read/parsed ? It would be easier to identify the corrupted one.
Comment 18 Vincent Panel 2006-07-07 13:05:10 UTC
According to the other bugs I've seen around, I guess this is an upstream problem with metakit not handling correctly corrupted archive files. So it should probably be reported here : http://www.equi4.com/cgi-bin/cvstrac/metakit/rptview?rn=4 but as I said, I don't know how to determine which file is corrupted. I would send it to you if I could find a way...

And also I'll attach a tarball for the ~/.kde/share/apps/akregator dir which makes possible to reproduce the problem. A little later I'll try to isolate the blaming corrupted file.

Comment 29 Gregor B. Rosenauer 2007-06-21 16:12:31 UTC
same here on Kubuntu Feisty KDE 3.5.7.
Akregator does not start but eats 100% CPU until killed.
Removing my feeds (the OPML-file) "help" in that starting Akregator produces a normal crash.
Only when removing the Archive-folder in .kde/share/apps/akregator, Akregator starts up normally again.
Mine is only 450K so I'll attach it here.
This has happened before already, so I know the procedure, but I don't know the cause. I am using Akregator embedded in Kontact, maybe the Akregator-Archive got corrupted when Kontact crashed.

problematic feed-archive

when uncompressing this archive to your akregator-configdir, akregator will
crash at startup.

You can check your files with the utilities on their page.
http://www.equi4.com/metakit/stats.html

I had a problem with my harddrive and a file got corrupted. Unfortunately it cannot repair, but the one defective file removed, everything works again :)

reproducet with openSUSE 10.3. KDE 3.5.7 novell bugzilla #371701. I am contacting Frank with PM. 
Comment 34 Thomas Koch 2008-04-15 09:27:57 UTC
I had a similiar problem. For me akregator just freezed. I did a 
lsof -p AKREGATORPID
to see the files opened by akregator. The last file opened was a .mk4 file inside ~/.kde/share/apps/akregator/Archive

You can get the AKREGATORPID with 
ps aux|grep akregator

After renaming the last file listed by lsof, akregator started again, but the respective feed did not have any archived entries anymore. Now I'd like to know, how to resque a corrupted .mk4 file...
Comment 35 Chris Fritz 2008-06-01 00:11:10 UTC

Working and broken copies of an .mk4 file, and associated feeds.opml file.

This zip file contains a data folder with the feeds.opml and an Archive folder
with two .mk4 files.

One .mk4 file is my original from using a KDE 3.5 release of Akregator (program
version unknown, I'm afraid).  This one has .BROKEN appended to the filename.

The other .mk4 file is one freshly created by Akregator Version 1.2.50, on KDE
4.00.72, everything installed on Fedora 9 via from RPM.

I use Okteta (or KHexedit on KDE 3.X) to view the files and modify them.

(Note: At roughly location 0x23A0 in the .BROKEN file, the text is corrupted. 
This has no negative impact on loading the file.)

The .BROKEN file ends at roughly location 0x24020.  At this point, the .WORKING
continues with more data.

If I delete the contents of .BROKEN from 0x3F00 to the end of the file, and
then paste onto the end the contents of .WORKING from 0x23F00 to the end of
that file, the .BROKEN file will load successfully in Akregator (assuming I've
renamed it to remove the ".BROKEN" from the filename).

I don't know how to put together an environment for editing/building source
code, so I can't look into this problem in any more depth.
Comment 36 Chris Fritz 2008-06-01 00:13:41 UTC
Correction to my comment:

"If I delete the contents of .BROKEN from 0x3F00 to the end of the file"

...should read:
If I delete the contents of .BROKEN from 0x23F00 to the end of the file

I think the same thing of G.Christ in comment #43.
Comment 45 Datradan 2008-08-17 11:50:53 UTC
I've found why akreagator crash,
in ~/.kde4/share/apps/akregator/data/feeds.oplm , when I increase maxArticleNumber over my number of feeds saved, and I set archiveMode="globalDefault", akregator will not crash.

I hope this is useful to resolve this bug :-)
Comment 46 G360 2008-09-26 06:02:41 UTC
I have still the same issue, but now in openSUSE 11 with KDE 4.1.1 and Akregator 1.3.1.

If the saved feeds number is bigger than the limit to save, Akregator will crash at the next startup.

I Played arrount a bit with the maxArticleNumber and removed the archiveMode="globalDefault". I wasn't able to crash Akregator 1.3.3 at startup.

I have installed kubuntu 9.10 karmic and this bug has been fixed in Akregator. I have been able to import a huge number of feeds without problems.

Great!

I think I might have solved the bug, at least for me...
You just delete feeds.opml and it should work... But you do lose all of the feeds....

Comment 97 Tristan Miller 2009-12-10 12:08:38 UTC
As per Comment #94, deleting feeds.opml has suppressed this bug for me.  As I don't use Akregator any more, this is an acceptable workaround for me, though obviously it may not be for others.
Comment 98 Martin Steigerwald 2009-12-10 13:08:48 UTC
Strangely enough I have not seen this in ages. I think last time I had such a crash was with some KDE 3.x version. I do not thing I had Akregator crashing at startup with any KDE 4.x version - currently using 4.3.2 debian packages. And I use it with a quite insane amount of newsfeeds ;-). At least more as 50 estimated  quickly totalling to more than 139600 unread messages. My ~/.kde/share/apps/akregator directory is 303MiB big.

Would be interesting to know who updated akregator with data from KDE 3.x to 4.x and who started clean with 3.x. Maybe on update it might make sense to recreate feeds.opml?
Comment 99 Martin Steigerwald 2009-12-10 13:10:06 UTC
thing=>think. And who started clean with 4.x of course.
Comment 100 Nicolás Alvarez 2009-12-10 13:40:01 UTC
I think this is pretty simple. If your amarok is crashing, and moving feeds.opml away* makes it stop crashing, please post your file here so a developer can reproduce the problem, since it must be a problem in it.

(* Don't delete it!)
Comment 101 Christopher Heiny 2009-12-10 17:05:00 UTC
Discarding all feeds is *not* an acceptable solution, especially for those of us with large numbers of feeds.  Sort of in the line of "removing the patient's head to prevent further sneezing" :-)

Anyway, yesterday afternoon I pulled down the latest Fedora 12 updates, and this problem has mysteriously cured itself (at least on my machine).
Comment 102 Nicolás Alvarez 2009-12-10 21:42:58 UTC
Well, I wasn't saying removing all feeds was a *solution*.

"If replacing the patient's head makes him stop sneezing (which some people -*already* tried), the problem was indeed in the head; please sends us the old head so we can track down the sneezing cause in more detail" :)

Comment 104 Mark Rose 2009-12-12 07:50:17 UTC
This feed was causing akregator to crash on startup, and crash when I add it.

http://feeds.feedburner.com/corbettreport_articles

It does NOT parse correctly. Here is the malformed entry:

            		<item>
                        	<title>UK Group Proposes Using Carbon Offsets to Stop Poor From Breeding</title>
                            	<description>Carbon hysteria reaches its logical conclusion</description>
                            	<linkhttp://www.corbettreport.com/articles/20091209_optimum_population.htm</link>
	              	</item>

Apparently this wasn't an issue, as until I upgraded to Kubuntu 9.10 (with KDE 4.3.2), I never had this issue with this malformed feed (I've been starting Kontact successfully every day).
Comment 105 Dominik Tritscher 2009-12-12 09:36:38 UTC
I can reproduce the crash with the feed posted by Mark Rose using KDE 4.3.4 from Kubuntu packages. But according to the backtrace, this seems to be a QT issue not an akregator one. But anyway, here is the backtrace:

I just rebooted my computer the second time after upgrading to KDE SC 4.4.0. Akregator just crashed right after login, I was not doing anything special.
Comment 118 Juha Tiensyrjä 2010-02-11 09:50:17 UTC
I just found out that removing the feed cache files solved the problem. It may be that the abrupt power loss of my computer caused some corruption which manifested as a crash on startup.

Sorry, my bad. I should've checked the situation more carefully.

I went through my mk4 files one at a time, and found one which causes the problems.  Renamed it and off we go.
file:///home/laptop/.kde/share/apps/akregatorold/Archive/http___minneapolis.craigslist.org_search_sss%3Fquery=auction&format=rss.mk4old
I can send the file to anyone if it will be useful to them (but it is 11.2Mb)

New crash information added by DrKonqi

First time running Akregator after a power outage and, it crashes immediately; the main window doesn't even appear. Renaming/deleting $KDEHOME/share/apps/akregator/Archive allows Akregator to run normally. Alternatively, deleting $KDEHOME/share/apps/akregator/Archive/archiveindex.mk4 (without touching any of the http___*.mk4 files) allows the main window to appear, although that leads to another separate crash after a second or so. I could provide the mk4 files if needed.

Re Nicolás, comment #149: Nicolás, I don't think there is a contest amongst developers who gets the most duplicate reports. Maybe there are no active    aKregator haxx0rz at the moment? Does anyone know the state of Akregator maintenance? I will ask on kdepim in a moment.

Aside from that: Betatesters *should* look for duplicates and usually in the reporting process Bugzilla presents possible duplicates. How >100 bug reporters fail to see those duplicates actually is *completely beyond me*.

*Please watch out for duplicates!* It does not help the process to report the same issue again and again and again and again...

Subject: Does anybody know the state of Akregator maintenance?

Hello!

Does anybody know the maintenance state of Akregator? Are any aKregator haxx0rz still with KDE development?

I am asking cause

Bug 116482 -  metakit: akregator crashes at startup
https://bugs.kde.org/show_bug.cgi?id=116482

collects duplicates like dust without anyone apparently working on it.

Actually I cannot reproduce it at all since ages, Akregator just works for me, but AFAIR there have been several mk4-Files posted that should trigger the problem.

Anyone knows whom to contact about this?

Ciao,

I had a kernel crash and after REISUB'ing out of it Akregators archives was apparently corrupted thus giving this crash. Tried 3 times with Kontact; same crash. Tried stand-alone Akregator; same crash.
Now I hope I can get it running again without having to loose all the status of the archive :-/
Well the BT should be good anyways...

This is debian bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=590147 that does not allow akregator to release.

Please correct it before release.

Hey,
don´t know if it helps, but here is my crash report.
I think it was after a hang of the system.

Hey,

Here is my Archive: http://www.file-upload.net/download-2910539/Archive_old.tar.gz.html

I solved the problem:
rename the archive folder /home/.kde4/share/apps/akregator
start akregator and close it
copy the files in the new created archive folder
do NOT copy the index and backup file, use the new one instea:-)

Comment 220 Martin Steigerwald 2011-01-09 16:48:44 UTC
From what I read from the mails posted below this is unlikely to be fixed in the current "stable" pre-akonadi version of Akregator and the Akregator akonadi ports needs someone to work on it.

Please refrain from reporting the same bug over and over and - guess what? - over again. Dr. Konqi gives quite some help when it comes to check for duplicates. Reporting it a million times will not help a single bit in resolving this more quickly. So please either help with coding or keep quiet and hope that someone else does it. Or try to find someone to fix the bug.

Thanks.

I am the maintainer, but I am lacking both time and motivation to work on it. And nobody else appeared so far to take over.

The issue is known for a long time, and easy to trigger, by using any corrupted mk4 file. The problem is that metakit allocates memory after reading the size of some value in the db. If that value is bogus, which means it's some random value, and far too high most of the time and the process either starts to allocate huge amounts of memory or just crashes (if the value is above the OS limit), or both.
The only real solution I see is to move away from metakit to Akonadi. That was started (krss) and is now lingering in the akonadi-ports branch, but it needs someone with both time and motivation (see above) to complete it.

No, currently there is nobody working on it.

> What is the current status of this port ?

The basics were working, but it showed some performance issues when importing larger rss archives.
The implementation also shows that it was started in the early days of Akonadi resource development and we wanted replace some of krss-specific models etc. by the new like EntityTreeModel.
And then I'd like to cleanup the resource implementation, which became overly complex by adding another layer of abstraction to support
both local storage and online RSS readers (newsgator in particular, which then closed down).

See Krenar's post. akonadi-ports needs to be rebased against current trunk though.

I have found the bug in the metakit package and proposed to debian to upload a new metakit in order to raise exception instead to crash

Will solve this bug
Comment 231 Samuel Brack 2011-03-02 13:38:19 UTC
Bastien, is there a patch available yet? If yes, we'd appreciate it if you'd upload it here, too.
Comment 232 roucaries.bastien+bug 2011-03-02 13:46:15 UTC
see http://git.debian.org/?p=collab-maint/metakit.git;a=summary patch branch is debian-patches/2.4.9.7-1

Will not fix the crash but instead of segv raise exception

Comment 242 Andrei Slavoiu 2011-07-04 23:46:20 UTC
For anybody hitting this issue, here's an easy way to identify the corrupt mk4 file:

cd ~/.kde4/share/apps/akregator/Archive
for i in *.mk4; do echo $i; ./mku.linux $i > /dev/null; done

Each file name followed by "Segmentation fault" is corrupt and should be removed in order to successfuly start akregator.

I wouldn't say so, because I couldn't find where I could get this ./mku.linux executable.

Another way to detect which mk4 file in ~/.kde4/share/apps/akregator/Archive/ causes Akregator to crash is to use strace to trace the akregator process to find out which file it (opens and) reads last. Just move the corrupted file somewhere else (in case you need to restore the data somehow) to get akregator running again. One might have to do this multiple times if multiple files are corrupt.

When oh when are you KDE guys going to add a decent backend to akregator?! Akregator is destroying my feed data too often and it's getting my the nerves. And there seems to be no recovery option *sob* =[
Comment 251 Andrei Slavoiu 2011-11-25 11:34:53 UTC
I don't remember exactly where I got the mku.utility initially, I must have copied it there and later thought Akregator installed it... Anyway, a google search revealed it's part of the mkstats.kit utility http://equi4.com/metakit/stats.html

Comment 275 squan 2017-09-14 13:51:17 UTC
The correct location of feeds.opml seems to be  in ~/.local/share/akregator/data (and not in .kde4 as it used to be in earlier times of this issue).

After a failed resume from suspend to RAM (which since several weeks is a common experience with openSUSE Leap/Tumbleweed with both NVidia and AMD graphics) my feeds.opml got corrupted (Bug 384207).
Is there a backup to be found somewhere may be?
Comment 276 Orivej Desh 2017-09-14 15:39:30 UTC
The only backup is feeds.opml~ in the same directory.
