Bug 291240

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.7-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I have an application launcher widget on my desktop, and I clicked on it to logoff, at which time plasma crashed.  This happens randomly and infrequently.  It is more likely after I have been changing my desktop settings.  This time I had changed my desktop theme and customized window settings.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
