Application that crashed: kmail Version of the application: 1.11.90 KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 139" Qt Version: 4.5.1 Operating System: Linux 2.6.25.20-0.4-default x86_64 What I was doing when the application crashed: kmail has been pretty good on kde4 beta 2 thus far. I can't pinpoint what caused it to crash this time. A few minutes before the crash, I had moved several messages to the trash, but then decided I needed to reply to one of them. I selected the trash folder, found the message, sent my reply, and then went about my business going through several other emails. Without warning, kmail just disappeared and the crash assistant appeared and provided a 3-star backtrace. So here it is. This is a very basic configuration of kmail with only 1 pop account configured so far. I have a number of folders, but just one pop account. Let me know if you need anything else. -- Backtrace: Application: KMail (kmail), signal: Segmentation fault [Current thread is 0 (LWP 19584)] Thread 2 (Thread 0x41a8c950 (LWP 20102)): #0 0x00007f25b22f705d in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007f25b2567f87 in QWaitCondition::wait (this=0x1d22448, mutex=0x1d22440, time=30000) at thread/qwaitcondition_unix.cpp:85 #2 0x00007f25b255db0a in QThreadPoolThread::run (this=0x1d22610) at concurrent/qthreadpool.cpp:140 #3 0x00007f25b2566ff2 in QThreadPrivate::start (arg=0x1d22610) at thread/qthread_unix.cpp:189 #4 0x00007f25b22f3040 in start_thread () from /lib64/libpthread.so.0 #5 0x00007f25b07a108d in clone () from /lib64/libc.so.6 #6 0x0000000000000000 in ??

This crash is happening during checking for new mail, but for me it looks like a memory corruption problem, which happened some time before that function. (This crash points do the QHash<...>::clear() method in PopAccount::processNewMail()) So without being able to reproduce, I can not do anything further with that issue, therefore I close it.
