Bug 234637

Version:            (using KDE 4.4.2)
Compiler:          gcc (GCC) 4.4.3 20100127 (Red Hat 4.4.3-4) 
OS:                Linux
Installed from:    Fedora RPMs

Application: ksmserver (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.11-99.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
Just after I updated KDE from the (fedora) rawhide repository I got a ksmserver crash and kde cannot be loaded.
If I get in with, for example, openbox it's impossible to open other programs as systemsettings or ksysguard which backtrace is the same from #5 to #7 (both systemsettings and ksysguard).

The crash can be reproduced every time.

 -- Backtrace:
Application: El gestor de sesiones de KDE (ksmserver), signal: Segmentation fault
