Version: 1.9.1 (using KDE 3.5.1 Level "a" , SUSE 10.1) Compiler: Target: i586-suse-linux OS: Linux (i686) release 2.6.16.13-4-default I had set-up an imap account, that I was checking, and the checking was going on a bit slowly. I then deleted the account, and after closing the configuation dialog I saw that it was still checking the account (this is a different bug). Then I clicked on the arrow that opens the progress bars (the one in the bottom of the window) and clicked on the red button to stop downloading unuseful messages. Kmail suddenly crashed.
Can you still reproduce and if yes, could you provide us a backtrace please?
Yes I can reproduce the bug on kmail 1.9.5. Unfortunately I can't provide a backtrace. I downloaded the necessary -dbgsym package from ubuntu, and reproduced the bug, but when the "crash dialog" pops up, it deadlocks with only a few lines of backtrace. If I run kmail in gdb, no need to say it, I can't get a bactkrace at all (I suppose it is because the kmail process is wrapped in the crash capturer process). If you can give me hints on how to get out of this, I will be happy to help. However it is really easy to reproduce the bug if you have an imap account (just ... be quick in deleting the account, but since kmail takes ages on disconnected imap, it will be easy).
Try running kmail with "--nofork --nocrashhandler" from within gdb. The first allows you to get a backtrace, whereas the second enables getting a core dump. ( You need to have run 'ulimit -c unlimited' before running gdb for the core dump though )
Ok, here it is, I hope it is useful, let me know if you need something more. Program received signal SIGSEGV, Segmentation fault. [Switching to Thread -1249953344 (LWP 7221)] 0x0842abf1 in ??
