Bug 362415

Application: konsole (15.12.3)

Qt Version: 5.5.1
Operating System: Linux 4.5.0-ck1 x86_64
Distribution: Ubuntu 16.04 LTS

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

Clicking away from konsole caused an instant crash.

Apparently a duplicate bug of 361934 but thanks to bug 355807 I cannot attach it to the duplicate.

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