I have a thread in my inbox from a mailing list and I've created a filter to put the messages belonging to that list in a folder and rewrite the header meantime. When I apply on a thread, KMail CVS HEAD crashes (using KDE CVS HEAD). The crash is reproducible on the same thread and the backtrace is here: Using host libthread_db library "/lib/libthread_db.so.1".

Andras, does copying the thread to another folder make any difference? If it still crashes, can you provide the thread to me via private mail, as zipped mbox (File -> Save as). Thanks.

Reopen
The problem is caused by an invalid "parent" in kmheaders.cpp lines 1040 ff. It's easy to reproduce following the description in the original post. There is no problem if the source folder is not threaded.
*** Bug 94304 has been marked as a duplicate of this bug. ***
To make things more clear: KMail crashes when he subject header is rewritten for messages which are moved out of a folder in subject threading mode using filters. Other cases are no longer reproducible.
*** Bug 97322 has been marked as a duplicate of this bug. ***
CVS commit by tilladam: Find a way to do subject threading without needing to have the subject remain stable during the lifetime of a message. In other words, don't crash when changing the subject header of a message which is part of the current subject threading trees. Pfew, this one was a bugger to fix.

it is still there in kmail final in 3.4.0
Reopen since it is reported now with kmail 1.8
Tobias, can you please provide detailed information about how to trigger that crash? I would like to see a backtrace as well. We've put considerable effort into analyzing and fixing that threading crash. Perhaps we've overlooked a constellation, but we need help to track this down further. Please make sure as well that you didn't run into http://bugs.kde.org/show_bug.cgi?id=97274 which is slightly different.
sorry i can't reproduce this again, but wait i deleted 3 clamav filters, perhaps this is the reason why this is not happening anymore. have to look at it further tomorrow.
hi i added again the clamav filter and then here we go: it crashed kmail in a way that it can happen, that the index files of maildir are damaged and mails appear with nothing in it and when you try to delete those mails the next one becomes the same as the deleted one. A real horror. deleting index file of the maildir helps to get rid of this again. (no debugging symbols found) Using host libthread_db library "/lib/tls/libthread_db.so.1".

Hm, the backtrace is not that usefull. Did you compile with full debug info? Can you describe what the clamav filters are supposed to do? Can you provide a folder containing as few messages as possible which triggers the crash when filtering? Do you use an IMAP account? Do you update that account while filtering?

I did not compile it myself, this is the version that shipped with SuSE 9.2 professional. (1.7.1 from KDE 3.3.0 as of the Info box.) > Can you describe what the clamav filters are supposed to do? I have usually filters that place mails in folders for mailing lists. I used manual filtering to move mails from one folder from different mailing lists in sub folders, since the main folder got too full. > Can you > provide a folder containing as few messages as possible which triggers > the crash when filtering? I copied the messages to a test folder and tried to reproduce the crash, but without success. Maybe I already lost the mails that triggered the crash? > Do you use an IMAP account? Do you update that account while filtering? No, all messages were fetched with POP and local on my hard disk, when that crash occurred. Robert
hi sorry archlinux uses strip and no-debug on packages i have a folder with approx. 100 mails. and there i use apply filter and then the crash happens. to get the clamav filter use the wizard in kmail. then it adds a rule to filters. clamav is a virus filter provided as wizard in kmail. i don't use imap in kmail. the problem happens when you use the filters on already received messages.
Robert, the problem was worked on in KMail 1.8, if you use version 1.7.x then you will have to further live with that crash. Tobias, what are your settings for the folder? Do you thread messages? If yes, is threading on subject activated? Does it crash when you filter the messages while threading on subject is deactivated? Does the crash happen after a restart of KMail when the index files for that folder have been deleted before? Could you "tgz" the folder in question and send it to me in private mail? Then I could try to reproduce the crash. Sorry for those many questions, but this crash is extremely difficult to hunt down.
ok here my answers: yes i use threaded view on the folder, it doesn't matter if threading on subject is also activated. the crash doesn't happen when threading is disabled. Deleting index files doesn't help. it happens also when only 2 mails are threaded and you apply the filter on it. you don'T need masses of mails 2 mails are enough. It only happens when i add the /opt/kde/bin/kmail_clamav.sh to the filters. overthe antivir wizard or by hand that also doesn't make a difference. perhaps the script has something bad in it that doesn't work with threading.
Tobias, is there any chance that you can use KMail from CVS? There has been a fix for filtering messages in threaded folders about two days ago. The fix will be in KDE 3.4.1, a similar problem has been reported to be fixed by that (102134). I think I gonna check clamav myself, but this might take some time though. So if you could test the CVS version, this could save me some effort.
Closing as success of a recent fix was reported in private mail. (it was the double pointers in the list thingy)

Bug 112480 was marked as a duplicate of this bug. However, I do not have any filters in place nor, do I believe am I using threading. I configured KMail to point to an existing IMAP mailbox with messages and folders. As soon as I tried to delete a message, the crashing started. So, I'm not sure this is a dup of this bug at all.

Either this bug is NOT fixed, or there is another real bug wandering about (reports #112480, #112953, #123949, #126589, etc...) which is being improperly being marked as a duplicate of this bug. I'm getting 100% reproducible crashes with Kmail 1.9.3, released AFTER this bug was supposedly fixed. The backtrace is compatible with the bugs listed below. The crash happens on QGDict::look_string(). All the following bugs were (directly or indirectly) marked as a dupe of this one, but ALL of them reports crashes on QGDict::look_string(), which was NOT reported on this bug. And these reports were reported for NEWER versions of Kmail: Bug 105242 - kontact closes when deleting message from imap account Bug 110113 - crash on marking spam or filtering Bug 112480 - KMail crashing when deleting messages from an IMAP account Bug 112816 - crash when emptying trash while having it open Bug 112953 - Kmail stürzt ab, wenn ausgewählte E-Mails in anderen Ordner verschoben werden sollen Bug 114072 - Kmail crash on deleting mail with the DEL key Bug 123949 - kmail crash while deleting subfolder of local trash Bug 126589 - moving a group of mails to the trash from an imap account crashes kmail Bug 127293 - SIGFPE crash when deleting message from nested remote IMAP folder Bug 128880 - Crash when delete on IMAP So, it looks like we have ANOTHER bug here. Please, stop marking bugs as dupe of this one, and reopen this issue (or one of the ones wrongly marked as duplicate).
CC: thiago@kde.org Thiago, since you were marking the bugs as dupe of this one, please read my previous comment and check the proper action for these last reports.
Juliano, If you still encounter the problem, please provide the information necessary to reproduce it.
Philip: the information necessary is all over the 10 bugs I listed above. For the lazy: With kmail 1.9.3, KDE 3.5.4, "Threaded message list" enabled, no filters, inbox of an IMAP account. I click on the "Date (Order of arrival)" header and kmail crashes. If running inside kontact, it crashes also. If I select a message and try to move it to another folder, kmail crashes. If I select a message and try to delete it, kmail crashes. The backtrace is always similar to the bugs listed above. Always on QGDict::look_string().

If I select a message and try to delete it, kmail crashes. Juliano, if it were that easy to reproduce, it would have been fixed for long. If I follow your advice, KMail doesn't crash at all. The main problem to make the crash reproducible is to describe exactly the constellation of some threaded messages which causes KMail to crash. I even had cases were it was not enough to send the content of a folder to a developer. His system didn't crash, but mine did. In the end, he was able to provide some patched files for me. In turn, I had to compile KMail based on that patches and send back the output. It took some iterations to get that specific constellation fixed. So, it's understandable that this bug report was marked as fixed after several constellations have been fixed. After every fix you think, this was the last place which broke the application. Unfortunately the threading algorithm seems to be all but easy. If you want to make KMail a lot more stable, consider switching off the threading options.
I have some news. With what you said, I tried running KMail on my laptop, with an exact copy of my desktop's home directory, and it didn't crash. The same content of the whole ~/.kde folder, the same operating system (Fedora Core 5), the same version of KDE and KMail. It is very strange that I can reproduce the bug in only one computer, while everything, except for the hardware, is identical. I also tried the suggested workaround in bug 133812 (cmt 3) - deleting the lock file - and the crashes disappeared temporarily. I could reorder the messages, delete messages and move them around, but then, kmail crashed while opening an attachment. Of cource, a new lock file was left in kmail directory, and the problem reappeared.
