Bug 282354

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.7-default x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: Restarting the system. Prior to shutting down the system I used free to see that there was very little swap in use (i.e., there was no memory leak issue). System was acting "slow" - hence the look at "free".

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
