Version: (using KDE 4.2.1) OS: Linux Installed from: Mandriva RPMs I was moving some nested messages to a mail folder when kmail crashed. restarting kmail I saw the mail were transferred, and wasn't able to reproduce the problem. here the backtrace: Application: KMail (kmail), signal SIGABRT [Current thread is 1 (Thread 0xb4ac26d0 (LWP 7715))] Thread 1 (Thread 0xb4ac26d0 (LWP 7715)): [KCrash Handler] #6 0xffffe424 in __kernel_vsyscall () #7 0x4e7a2c00 in raise () from /lib/i686/libc.so.6 #8 0x4e7a4668 in abort () from /lib/i686/libc.so.6 #9 0xb705cfd5 in qt_message_output () from /usr/lib/libQtCore.so.4 #10 0xb705d0cc in qFatal () from /usr/lib/libQtCore.so.4 #11 0xb705d1c5 in qt_assert () from /usr/lib/libQtCore.so.4 #12 0xb77f5f52 in ??

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? You need to install the "kdepim4-debuginfo" package (or something similar) Thanks :)
Sorry, I'm unable to reproduce the fault. However when I had the crash, I was moving messages and I was not sure where to put them, for that reason I spent a lot of time (maybe 10-15 seconds) looking for the right destination folder. From the backtrace it is possible to see (at #28) that the processevent was managing a timeout event. It seems that in the same moment I dropped the messages (concluding the message movement action) a timeout expired and the routine that manage the timeout hitted a variable with a wrong value, triggering the qt_assert at #11. In my opinion that variable was modified by the routine that move the messages, but the processevent stopped that routine before its end; then processevent started the timeout management, which found the wrong value in the variable and then asserted. my 2 cents Tom
Changing the status.
