Version: (using KDE 4.2.0) OS: Linux Kmail very often crashes when im moving many mails to another imap folder. This occurs on three different imap accounts, each on different server.
If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)
Marking as NEEDSINFO
I can reproduce this. what I've done: 1)create new sub-folder (imap account, don't know if this step is required) 2)select several emails and move them to that new folder 3)when emails are still being moved, open that folder result> kmail not responding for some time and then crash it seems it hangs in loop for some time reproduced with kde 4.2.98, kmail 1.12.0 I have core files, generating backtrace (for 12 minutes now, stack depth 1500 and still going), I'll attach backtrace when done
huh... over 55 minutes and still going... complete stack depth is almost 50 000 I'll keep core files for some time, let me know if compete backtrace is really needed. some info: top: #0

Created attachment 36066 [details] backtrace
This looks somewhat related to the backtrace in bug 201371. Also, the large of the backtrace can be a sign of stress (matching the "very busy" state of bug 201371 case) Have you noticed any other strange behaviour that would be caused by some Hardware problem ? Thanks for the BT.
(In reply to comment #7) > This looks somewhat related to the backtrace in bug 201371. Also, the large of > the backtrace can be a sign of stress (matching the "very busy" state of bug > 201371 case) in 201371 I don't see this part of pattern from my backtrace which is (I guess) important for this "loop" #21 0x0000003d8db54fdc in QMetaObject::activate (sender=0x4333ac0, from_signal_index=<value optimized out>, to_signal_index=<value optimized out>, argv=0x1) at kernel/qobject.cpp:3113 #22 0x0000003d8db39a45 in QAbstractItemModel::reset (this=0x4333ac0) at kernel/qabstractitemmodel.cpp:2263 It seems to me (it's only guess) there is some "onchange" signal which calls something that change something and emit signal again (or two signals) creating this recursion. machine is idle most of the time and works fine. It's very busy only when I reproduce this problem and it's busy because of loop filling up the stack. I didn't noticed any other crash so far. > Have you noticed any other strange behaviour that would be caused by some > Hardware problem ? no, this hardware is almost one year old, so I think it's quite new but seasoned. There is nothing indicating any problem. I can reproduce this bug at will with 100 % chance (using KDE 4.3.0 with KMail 1.12.0)
Bug 203624 got the same backtrace and situation. To organize this report: - As the "Michal" from comment 3 is not the same as the original report (I have messed up this): This report should be closed as NEEDSINFO/INVALID. (We are still waiting for the feedback of the original reporter). @Michal Hlavinka: I'm going to move the discussion of this bug to bug 203624. @Michał Gawroński (original reporter): if you can reproduce the original crash again; please open a new bug report. Regards and sorry for the noise.
