Description Josh Berry 2005-05-20 18:54:45 UTC
Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.4.3 
OS:                Linux

When KMail attempts to check mail (using cachedimap against a Courier IMAP server), it sometimes will crash with the following backtrace:

Using host libthread_db library "/lib/libthread_db.so.1".
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.

Comment 1 Carsten Burghardt 2005-05-21 12:26:11 UTC
Thanks for the report, please compile kmail with --enable-debug=full to get a 
valid backtrace.
Comment 2 Josh Berry 2005-05-23 07:29:49 UTC
D'oh ... I didn't catch the fact that debug wasn't enabled.  Sorry about that.  Here's a new backtrace for you:

Comment 3 Antonio Larrosa 2005-05-25 12:35:47 UTC
I got this bug (with same backtrace than previously posted) after compiling kdepim on 20/05.  I tried regenerating the index and even rebuilding the cache, but even if both worked as they're supposed to, kmail continued crashing when checking mail in my inbox folder.

I tried some previous revisions to find the commit that caused the problem. svn commit number 413366 already was buggy, then I tried the previous kmail version I was using (just to see that the bug didn't happen with that one) and it worked fine (it checked and downloaded mails correctly), then I tried again one of the buggy versions, and it worked fine.

It seems using the working version somehow removed the cause of the problem when neither regenerating the indexes nor rebuilding the cache did that.

So it works now, and all I can say is that the bug was committed between the 25/03 and revision 413366. 

Btw, the crash happens at 

   if (msg->isOfUnknownStatus() || !(flags&1) ) {

(currently at kmfolderimap.cpp:1333 in svn). I run the bad kmail under valgrind and it said that the problem was that msg was already deleted.

Hope that helps.
Comment 4 Antonio Larrosa 2005-05-30 21:23:43 UTC
I got this problem again, so I tried several revisions until I found the change that introduced the bug: 409056 .
409055 works fine, so using svn diff -r 409055:409056 shows the change that breaks it.

Please CC me if you reply to this via mail

Comment 5 Josh Berry 2005-07-19 19:05:15 UTC
This bug also occurs with regular IMAP, however, it occurs when selecting a folder to see what messages are inside it.

My off-the-wall guess is that this is somehow related to the saved-search folders... I will try removing mine and see if that stops KMail from crashing.

Here is some hopefully-useful information from Valgrind and KMail's debug output:

Comment 6 Josh Berry 2005-07-19 19:11:25 UTC
Sure enough, getting rid of my saved searches stopped the crash.

When I attempt to start a new search, I get the search dialog, enter in my search terms, click "Search", and ... crash.

I'm not sure if details from that crash should go into this bug, or if I should open a new one.
Comment 7 Till Adam 2005-07-21 22:44:05 UTC
SVN commit 437417 by tilladam:

Don't unget messages we did not get ourselves.

Antonio, does that help with the crash?

I can't reproduce this crash anymore, so I'm assuming Till's commit fixed it.

As the reporter, I'm going to go ahead and close this bug.

Comment 13 Ber Kessels 2005-12-01 10:31:21 UTC
I have tried this in a clean profile, with both Cached IMAP and ordinary IMAP. The crash still occurs. Hopefull this will help a liitle: 
* The crash happens also when I have kmail running in the background (no directories are opened/changed).
* I have no searches defined.
* It (seems to) happens only when imap is being "refreshed" or "receive messages" or when the interval check retreives new messages. 
* I did not see this crash happening when there was no new mail on the server.
* It only started happening after upgrade to 4.5 (kubuntu breezy)

Thanks, Bèr

Comment 14 Ber Kessels 2005-12-09 08:49:14 UTC
Is there anything I can do to help fix this bug? It is gettign annoying, having to re-start kmail at least once an hour. (thunderbird is peeking around the corner by now, shudder)
Comment 15 David Faure 2005-12-09 10:32:36 UTC
No idea about a workaround, but it would be useful if you ran kmail under valgrind,
to see why it crashes there again. Hopefully it's not like in the initial report since
that one was fixed.

Comment 19 Adam Porter 2006-01-17 20:22:58 UTC
Is there anything I can do to help get this fixed?  I had to downgrade to 1.8.3, and that required taking all of kdepim with it, of course.  You'd think that after all these months, it could be fixed, especially when the commit that caused it was found.  :/

partial valgrind output for crash in kmail while syncing dIMAP account
Comment 21 Adam Porter 2006-04-11 05:15:21 UTC
At <http://www.kde.org/announcements/changelogs/changelog3_5_2to3_5_3.php> it says:

    * Fix crash in disconnected IMAP (rev 526818)

Does that refer to this bug?
Comment 22 Adam Porter 2006-04-12 09:16:40 UTC
FYI, I've been using KMail 1.9.1 from/with KDE 3.5.2 and haven't had this problem yet, whereas before I got it a lot.  I'm guessing that it's fixed.
Comment 23 Adam Porter 2006-04-15 07:31:56 UTC
Well, I just got the same old crash, it just didn't happen as quickly as it did before.  I sure hope it gets fixed in 3.5.3 (sure would be nice if Debian could pull it in sooner).  Here's the backtrace:

Bug also exists in 3.5.5-r2 to 3.5.6-r3 in Gentoo, altough not using cachedimap, just "normal" IMAP.
Comment 36 Richard Homonnai 2007-05-03 01:59:26 UTC
Somehow it stopped altogether today. Maybe the mail server got updated or something....
I'm afraid I cannot provide any help in here now :(

I have got similar crash in gentoo kmail 1.9.7 kde 3.5.7 for pop3 email account. It appears very frequently.

Can provide crash information if required.

I believe I am experiencing the same or a related bug. KMail crashes often but not always upon checking a (disconnected) IMAP account. Despite the mention of filtering in the backtrace, no filters at all have been configured.

Happens both on current Debian testing (amd64): 
Qt: 3.3.7
KDE: 3.5.8
KMail: 1.9.7
and on a unstable/testing mix (the backtrace was obtained with this configuration):
Qt: 3.3.8b
KDE: 3.5.9
KMail: 1.9.9

Comment 42 Gunter Ohrner 2008-04-02 11:09:58 UTC
I got the same crash Boris did, at least according to the backtrace. I get it in a different situation however: kMail 1.9.9 with KDE 3.5.9 on Linux IA32 (Debian SID) always crashes with this SIGSEGV if I try to rebuild my inbox's dimap cache.

Does this look like the same bug, or should I open a new report so it can be tracked independantly?

Comment 44 Donatas Glodenis 2008-08-24 17:17:41 UTC
anything new about this problem? I am very disappointed, but i cannot use my time on email to try to trick it into syncing instead of working. 

I am curious, is dIMAP in Kmail maintained, or is it a leftover that no developer really understands or cares about?

I tried simple IMAP yesterday, but I cannot perform searches on those imap folders then, and it also seems to crash , maybe not as often, but still...

Is there any other decent KDE mail client with cached imap support?
Comment 45 Modestas Vainius 2008-08-24 17:51:58 UTC
kmail akonadi integration will fix this. However, that won't be earlier than KDE 4.2 or 4.3
Comment 46 Donatas Glodenis 2008-08-26 07:56:36 UTC
I noticed that a lot depends on the connection speed. Sync does not fail if connection speed is good. 

So, it is another year to wait, if it all depends on akonadi integration...

I hope this is more about the same bug.

What I see is:
kmail reads all the local imap folders, checks that all the local mails are still there, some of them are deleted in the imap server, and then rereads all the local imap folders, and then crash..

I'll attach a valgrind output, but I guess it does not contains the most precious traces, because it counsumed all the memory and crashed, but contains some valuable information.

SVN commit 900449 by tmcguire:

Fix a crash when syncing flags from a server while we have a search folder
that has a search rule which needs the complete body, because this unget()s
the message behind our back right after changing the flags.

BUG: 106030
