Application: kontact (4.7.0) KDE Platform Version: 4.7.00 (4.7.0) "release 10" Qt Version: 4.7.3 Operating System: Linux 2.6.37.1-1.2-desktop x86_64 Distribution (Platform): openSUSE RPMs -- Information about the crash: - What I was doing when the application crashed: Today I migrated from KDE 4.6.x to 4.7.0 and also to a new Kontact/KMail. The conversion went fine, according to the migration wizard. I gave the migration tool one-time access to my KWallet and Akonadi forever access. However, KMail did prompt for my e-mail passwords soon after the migration was finished. This may have nothing to do with the crash, but I'm mentioning it just in case. When Kontact was running after the migration, it was very unresponsive and there was a lot of harddisk activity. It wasn't swapping, so it must have been activity on files. I saw some mails pop up in the Inbox with subjects in blue, which were later filtered out to the mailbox they belong in. After a while, Kontact crashed while I was reorganising the width of the different panes. I restarted Kontact and didn't touch it and it continued to do something that caused harddisk activity and a while later it crashed again. And now if I start it, it crashes within seconds of being launched. I'm using local maildir storage for most of my mail and I have also configured a GMail account via IMAP. The crash can be reproduced every time. -- Backtrace: Application: Kontact (kontact), signal: Segmentation fault [Current thread is 1 (Thread 0x7ff59c4ab760 (LWP 9000))] Thread 2 (Thread 0x7ff585b26700 (LWP 9001)): #0 0x00007ff59485438c in pthread_cond_wait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007ff598ed21d4 in WTF::TCMalloc_PageHeap::runScavengerThread(void*) () from /usr/lib64/libQtWebKit.so.4 #2 0x00007ff59484fa3f in start_thread () from /lib64/libpthread.so.0 #3 0x00007ff599a7467d in clone () from /lib64/libc.so.6 #4 0x0000000000000000 in ??

Created attachment 62829 [details] Third backtrace, again similar but not the same Attached a third backtrace. Is it normal to have a 400-level call stack or did recursion go wrong? MailCommon::SearchRuleString::matchesInternal is in this backtrace 13 times...
Workaround found: if I edit ~/.kde4/share/config/kmail2rc to remove all my filters, KMail seems to be stable.
I waited until Akonadi had finished processing the contents of the maildirs and then re-added my filters 10 at a time (I have 44 in total). It seems to be stable now. So the bug might be some kind of race condition that occurs when new mails (from the point of view of KMail: the files are not new but their availability through Akonadi is) are coming in at a fast pace and there are a lot of filters defined. Or perhaps there is a problem if filters are moving mails to the same maildir folder that Akonadi is scanning.
comment 2 : I fixed it in kmail-4.7.1 Don't know for other crash.
*** Bug 287386 has been marked as a duplicate of this bug. ***
I haven't had any more of these crashes in KDE 4.8 and 4.9.
Thank you for the feedback.
