KDE Platform Version: 4.11.2 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

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

Launched KDE's "Start Menu" and launching Chromium through a shortcut, when Plasma Desktop crashed; generating an error report.

The crash can be reproduced sometimes.

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