Bug 325487

Application: konsole (2.11.1)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-9-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

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

I was switching tabs with Shift-Left,Right and moving tabs around with Ctrl-Shift-Left,Right. Nothing special was open inside the terminals, a python virtualenv asome shells. Can't alwyas reproduce this so it's likely not directly related to konsole.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
