This could be related to the glibc bug : bug 196207. Check this: - Quit Amarok - Start Konsole - Type "export QT_NO_GLIB=1" + Enter - Type "export MALLOC_CHECK_=" + Enter - Type "amarok" + Enter - Use Amarok and check if it crashes or not If it doesn't crash, then it is likely to be bug 196207. Nope, that doesn't help it, still crashes pretty similarly. Unfortunately it's a pretty unhelpful backtrace in that I don't see the signal handler being called anywhere. A couple things I *do* notice: - It doesn't seem to be crashing during the scan -- it seems to be crashing just after, when some other part of Amarok is being updated. So it might be a crash in e.g. the collection browser. - Those errors in your debug output are odd, because they're simply when copying over information from a temp table to a non-temp table. There should be absolutely no discrepancy between the columns. Has the scanning *ever* worked for you with the local server? My guess is that there is some sort of permissions problem or some such thing such that the DB is not actually usable, and somewhere down the line it's causing a crash.

New crash information added by DrKonqi
Looks like I just got the same backtrace.
Though I can't say what was in the console output.
And also this happened during incremental scan. What happenned:
1. Amarok was running (playing random playlist)
2. At the same time I was splitting one of my flac files into a smaller flacs using cue file and cuebreakpoints+shnsplit tools (in konsole)
3. As a result new flac files were constantly appearing inside my ~/Music directory
4. I think that amarok noticed that and started updating its database
5. It crashed (this crash I am reporting now)
6. I restarted amarok and it crashed again with the similar backtrace
Amarok is compiled from sources on 31 Dec 2009, git commit 25a1924e3f896c6fd8fa55d54ad9c2448240e43f

I was looking for a line like [Signal handler called] -- I didn't realize KCrash was replacing it. Hi,
I got the same crash (the same backtrace).
Gentoo
Qt: 4.6.0
KDE Development Platform: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
kde4-config: 1.0
I'm not sure whether this is possible as m_urlsHashByUid is defined as QHash
foreach( QStringList *list, m_urlsHashByUid )
delete list;
But even I commented it out, I got crash later:

I got the crash also when I cancel collection scanning or I exit Amarok during the scanning. Does anyone know of a specific way to reproduce this? It's very hard for me to make sense of what could be going on here because I have no idea how to trigger the crash. I just do a full scan. It is probably related to some files in collection. When I selected a directory with only several files, all were scanned and shown in collection. But after a while, Amarok crashed on different error in CoverFetcher. *** Bug 221106 has been marked as a duplicate of this bug. *** bt from bug 221106 [KCrash Handler] #5 0x00007fe49be0705d in ??

Let Amarok load up, then close it. Now, wipe the DB. Then do amarok --debug again, and this time capture the *full* output. (Either clear your scrollback, then copy and paste to a file, or try --nofork and start with something like "amarok --debug --nofork 2>&1 1>amarokoutput.txt"). Please also get me the backtrace associated with that particular run -- attach each as a file to this bug report. We've delayed tagging by 24 hours to try to get this solved, so the faster the turnaround time that someone can provide, and the more of you that can work with me on this, the better. Also, as Lydia said, try to find me at #amarok as jefferai if you can do some real-time debugging with me. Created attachment 39594 [details]
DrKonqi output and --debug output
I have now added the DrKonqi output and the command line output. The break is at line 243 for those two outputs.

Unfortunately I had not mysql compiled with debug infos, so bt contains ?? :-( I just compiling mysql with debug infos, will try again. After next start, amarok shows 7185 tracks in collection. I really don't know what to think about :-( Seems like I'm not able to reproduce the crash with blank database now :-(
With wipe database, amarok crashes at 98% with bt below. It doesn't mater whether I use embedded or standalone mysql. I tested with 5.1.40 and 5.1.42.

After restart, Amarok correctly shows collection scanned in previous run. Start incremental scan and works correctly.
When I now run full scan with data in database, I get BT below. Scan did not finish, Amarok crashes on 77%. And continue crashing in each start.

Patch against 2.2.2 tag
Hi guys/gals,
Please test this patch ASAP.
You need to be sure to apply this against tagged 2.2.2. To do this, do:
git reset --hard v2.2.2
If you have updated to current HEAD and built current Amarok, make sure you clean your build dir...if you've installed it onto your filesystem somewhere, try to manually remove those files -- the names of some libraries may have changed and you could end up with cruft making things confusing.
Let me know how it goes.
Thanks!
How boring is this, no more crash here after applying a patch. Thanks Jeff for your heavy work. (: Hopefully others have similar results. The patch does indeed solve the crash Jeff! But as you might already know, out of the two songs with identical MB ids, only one is added to the collection: the one that is scanned last I guess. (In reply to comment #42) > The patch does indeed solve the crash Jeff! > But as you might already know, out of the two songs with identical MB ids, only > one is added to the collection: the one that is scanned last I guess. Applicable to all on this bug: It's true. The identifier is supposed to be globally unique to that track. You can't exactly fault Amarok for thinking that a unique identifier shouldn't be shared by the same file. You should probably submit a report to MusicBrainz about this (though try retagging it in Picard first). There's a chance that most of you experiencing this crash have a similar situation -- two files with the exact same ID, either through duplication of a file tagged by amarok_afttagger or from MusicBrainz issues. If you have a random file not showing up in the collection, it's likely that this is the cause. The good news is that there is a workaround: 1) If there are duplicated MBIDs and those can't be fixed by Picard, run amarok_afttagger on those files (currently MP3s, Ogg/Vorbis, Ogg/FLAC, and FLAC is supported). The AFT tag is preferred over the MBID. 2) If they were already tagged with amarok_afttagger, then probably you have actual duplicate files, where the file was copied at some point with that generated value in the tag. In this case you can run amarok_afttagger with the --newid flag to regenerate them, which will re-randomize the values. commit d35f708aec3b882dfc26484f157ac028259444e8 Author: Jeff Mitchell <mitchell@kde.org> Date: Fri Jan 8 07:45:12 2010 -0500 Fix a crash in ScanResultProcessor's destructor. Despite all the extra checks I put for null pointers in the destructor, this wasn't actually the problem. The problem, which could occur in a few ways, was that in certain instances values were either not removed from a hash when they should have been, or added to a hash when they shouldn't have been. Then when the destructor ran, it would hit two values pointing to the same QStringList, and the second access would cause a crash. Thanks to Mikko for doing some heavy legwork helping me narrow down the cause, and Tm_T and hyper_ch for their help.

Despite all the extra checks I put for null pointers in the destructor, this wasn't actually the problem. The problem, which could occur in a few ways, was that in certain instances values were either not removed from a hash when they should have been, or added to a hash when they shouldn't have been. Then when the destructor ran, it would hit two values pointing to the same QStringList, and the second access would cause a crash. Thanks to Mikko for doing some heavy legwork helping me narrow down the cause, and Tm_T and hyper_ch for their help.

I just tested the patch (continue #37). After scan, amarok crashed, but not BT generated :-(
Then I started Amarok again - database was updated. I forced full scan. Amarok crashed again with following BT. I'll do more tests evening.

Marian, Is it possible for you to be available today on IRC and/or IM? It would really help if I can work through this with you directly...we want to get this patch fixed up for packagers before 2.2.2 releases. (You can email me contact info at mitchell@kde.org instead of posting here). Thanks! Hi,

Yes, that should really be fixed by now, Archlinux provides the patch. See also comment #3 in bug 222842 *** Bug 222438 has been marked as a duplicate of this bug. *** Application that crashed: amarok Version of the application: 2.2.2 KDE Version: 4.3.4 (KDE 4.3.4) "release 2" Qt Version: 4.5.3 Operating System: Linux 2.6.31.8-0.1-desktop x86_64 Distribution: "openSUSE 11.2 (x86_64)" What I was doing when the application crashed: So as in [Bug 215731] "Collection browser shows wrong cover" described, a full rescan is started in the amaroK settings dialog. The rescan starts (on the NFS-Mounted path) and send to a local MySQL database. No other tasks ar running, playlist is empty (works with 2.2.1 version fine - but crashes with 2.2.2 Version (from yesterday and today - from openSUSE 11.2 repository). The crash is coming short befor rescan is finished (in my case all 6 times at 97%). Additional Traces are in Bug 222438, if needed I make new tests. PS: But I don't understand in detail, what is to do to handle the workarround. *** Bug 222528 has been marked as a duplicate of this bug. *** (In reply to comment #59) > But I don't understand in detail, what is to do to handle the workarround. It is not a workaround, but a patch, normally the patched version should be available in OpenSuSE already. Ulf, please open a new bug. Your issue is probably not related to this. What is the different? But the Bug ist allways open as Bug 222438 (must be reopened?). It's a completely different backtrace. *** Bug 225207 has been marked as a duplicate of this bug. *** |
