Application: plasma-desktop (0.4)

-- Information about the crash:
This may very well be a duplicate of bug # 268157, but this is currently hard to verify for me considering my system is in the middle of a shutdown with just the crash reporter open...

- What I was doing when the application crashed:

Restarted the system via the "Lock/Logout" Plasmoid.
