Application: plasma-desktop (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Linux Mint 16 Petra

-- Information about the crash:
- What I was doing when the application crashed:
I played TF2 and then closed it. I did not have any programs running except Steam. Then when I wanted to start Firefox, or any program in the Application Launcher, Plasma Desktop crashes.

- Unusual behavior I noticed:
In the Application Launcher, the program entries did not have a blue rectangle around them.

I guess this is some type of problem with Valve's engine.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
