Bug 329154

Application: plasma-desktop (4.11.3)
KDE Platform Version: 4.11.3
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:
1) click on corner
2) click on "activity"
3) click on "add graphic components"

And then, a cloud of random pixels appears instead of the  list of choices.

Remarks :
- language is French
- running under VirtualBox 4.3.6 / 4 cores / 2GB
- not reproduced, works fine after the first attempt

The crash does not seem to be reproducible.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (plasma-desktop), signal: Segmentation fault
