Description Unknown 2009-06-08 23:13:53 UTC 
Version:           ismeretlen (using 4.2.88 (KDE 4.2.88 (KDE 4.3 >= 20090527)) "release 1", KDE:KDE4:UNSTABLE:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.27.21-0.1-default

I tried to kill `mc` but it was using hard-disk intensively, thus it was very hard to eliminate it. So I switched to tree view and tried to kill its parent, `bash`. During this, in a separate bash session I also tried to kill mc with `killall -9 mc`.

In the system manager mc and bash suddenly disappeared and then the whole manager crashed.

Here is the backtrace:

Comment 1 Dario Andres 2009-06-09 00:45:00 UTC 
This could be related to bug 158399. Thanks
Comment 2 John Tapsell 2009-06-09 00:53:31 UTC 
Oh boy.  I really hate bugs in the custom model.  It's nearly impossible to get right.  This is going to take _weeks_ to track down and fix, if I ever get the energy to attempt it.
Comment 3 Sebastien Martel 2009-08-02 20:37:05 UTC 
Is there a way to reproduce this I tried doing something similar with krunner but couldn't reproduce this error.

From bug 219077:
---
What I was doing when the application crashed:
Firefox (not Iceweasel) always hangs when I try to close it, so I went to kill
the hung process in System Activity app.  After killing Firefox, there was
another process 'mozilla.sh' (I think) and when I clicked that to see it, the
System Activity app crashed.

This should be fixed now.  Please reopen if it appears in 4.4 RC2 or newer.
