Version: (using KDE 4.2.1) Compiler: gcc-Version 4.3.3 (Gentoo 4.3.3 p1.0, pie-10.1.5) OS: Linux Installed from: Gentoo Packages I am subscribed to the Linux kernel mailing list and as such recevie around 400-1000 emails per day. I view them in threaded view and delete whole threads using ctrl+del. Once in a while kmail like to crash if I delete lots and fast. I have no backtrace yet, but I can see whether I can get some.
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 :)
Ok, just managed to crahs kmail by deleting emails in the thrash. I hope the backtrace is usefull, if not, sorry, I don't have time to do other steps.

BTW, I am using qt 4.5.0, in case it matters.
I think that I suffer the same type of bug. From time to time, when I select several messeges to delete at once, kmail crashes. It is not reproducible, beacuse it crashes randomly. The bakctrace is: Aplicació: KMail (kmail), senyal SIGABRT Thread 1 (Thread 0xb3f44920 (LWP 5259)): [KCrash Handler] #6 0xb8043424 in __kernel_vsyscall () #7 0xb5e65790 in raise () from /lib/libc.so.6 #8 0xb5e670c8 in abort () from /lib/libc.so.6 #9 0xb6a442d5 in qt_message_output () from /usr/lib/libQtCore.so.4 #10 0xb6a44397 in qFatal () from /usr/lib/libQtCore.so.4 #11 0xb6a44455 in qt_assert () from /usr/lib/libQtCore.so.4 #12 0xb77e0749 in KMail::MessageListView::Core::Model::viewItemJobStep () from /usr/lib/libkmailprivate.so.4 #13 0xb73342c3 in KMail::MessageListView::Core::Model::qt_metacall () from /usr/lib/libkmailprivate.so.4 #14 0xb6b3e1a9 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #15 0xb6b3e752 in QMetaObject::activate () from /usr/lib/libQtCore.so.4 #16 0xb6b75b77 in QTimer::timeout () from /usr/lib/libQtCore.so.4 #17 0xb6b4513e in QTimer::timerEvent () from /usr/lib/libQtCore.so.4 #18 0xb6b3af5f in QObject::event () from /usr/lib/libQtCore.so.4 #19 0xb61c701c in QApplicationPrivate::notify_helper () from /usr/lib/libQtGui.so.4 #20 0xb61cea9e in QApplication::notify () from /usr/lib/libQtGui.so.4 #21 0xb7e85cfd in KApplication::notify () from /usr/lib/libkdeui.so.5 #22 0xb6b2bc1b in QCoreApplication::notifyInternal () from /usr/lib/libQtCore.so.4 #23 0xb6b569a1 in ??

The later backtrace is unrelated and belongs to bug 174839.
