            Bug ID: 381226
           Summary: Konsole crashes in Wayland if closing window if there
                    is a running process
           Product: konsole
           Version: 17.04.2
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: mail at rainer-finke.de
  Target Milestone: ---

Application: konsole (17.04.2)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.5-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Close Konsole with the normal close button, I had an open SSH session, so the
Konsole asked me if I want to close even if there is an running process, after
confirming with yes Konsole will crash in Plasma-Wayland
- Unusual behavior I noticed:
I need a running process, only then I see the crash

The crash can be reproduced sometimes.

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