Bug 357108

Application: konsole (15.08.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.8-300.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

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

1.Docked the laptop.
2. Switched to console #2 (alt-f2).
3. Switched back to desktop (alt-f1).

I need to do this in order to get my external monitor activated after docking in. In docking mode only the monitor is being used.

The crash can be reproduced sometimes.

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