Application: kmail (4.10.5) KDE Platform Version: 4.10.5 "release 1" Qt Version: 4.8.4 Operating System: Linux 3.7.10-1.16-desktop x86_64 Distribution: "openSUSE 12.3 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: Exited kmail with ^Q intentionally, but the process didn't exit. Then I noticed I still had a composition window open - oops. I finished that email and sent it - the notice in the Notifications was that it was successfully sent. I was then expecting the kmail process to exit. When it didn't, I started another kmail, and got drkon It appears the newly started kmail crashed. user 23353 6.0 0.7 1688232 117092 ?

I have the same problem: KMail does not terminate its process when I close it. Also Kontact with KMail does not terminate too. If I attach with GDB to such a kmail, it shows the following: (gdb) info threads Id Target Id Frame 5 Thread 0x7f475b682700 (LWP 11958) "QProcessManager" 0x00007f477ac5fb33 in select () from /lib64/libc.so.6 4 Thread 0x7f475ab1d700 (LWP 11961) "kmail" 0x00007f4778c9310c in pthread_cond_wait () from /lib64/libpthread.so.0 3 Thread 0x7f475a21c700 (LWP 11963) "QThread" 0x00007f477ac5d64d in poll () from /lib64/libc.so.6 2 Thread 0x7f470362b700 (LWP 12004) "Thread (pooled)" 0x00007f4778c934de in pthread_cond_timedwait () from /lib64/libpthread.so.0 * 1 Thread 0x7f477d8f8780 (LWP 11925) "kmail" 0x00007f477ac5d64d in poll () from /lib64/libc.so.6 KMail 4.12.2
I believe that the cause of the problem is here, but not in the bug 319574, i.e. that KMail does not terminate correctly
