Application: konsole (3.0.1)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-30-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Switched back to konsole

This bug's back trace is equivalent to the one from #345691, but this damn KDE crash reporting assistant won't let me set this. grrrr

The crash can be reproduced sometimes.

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