Bug 255436

Application: ksmserver (0.4)
KDE Platform Version: 4.5.71 (4.6 >= 20101005)
Qt Version: 4.7.0
Operating System: Linux 2.6.36-desktop-1mnb x86_64
Distribution (Platform): Mandriva RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Selected logout with 'confirm logout' option selected as active.

- Custom settings of the application:
Logout started breaking again for $USER regardless of whether 'Desktop Effects' were on or off. 
I noticed the confirm logout dialog was not displaying so DISabled it in preferences. Result was that I could logout witout crash > 6 times.
I ENabled the 'confirm logout' option, applied it and tried to logout. Result is this crash. 

Apparently the 'confirm logout' widget is somehow breaking the logout.

The crash can be reproduced every time.

-- Backtrace:
Application: The KDE Session Manager (kdeinit4), signal: Segmentation fault
