Bug 331639

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:
Añadir una barra de tareas y un gestor de ventanas al escritorio.
- Unusual behavior I noticed: plasma se detuvo y reinicio mientras estaba redimensionando el gestor de tareas

The crash can be reproduced sometimes.

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