Bug 394453

Application: konsole (17.12.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-20-generic x86_64
Distribution: Ubuntu 18.04 LTS

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

Konsole seems to crash on wayland when closed with a process running. I just open a process without detaching, like docker, or kate., then keep it running and close konsole. A dialog asks me if I'm sure I want to close. Then the crash happens. Tried a few times and the crash always happened.

The crash can be reproduced sometimes.

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