            Bug ID: 356203
           Summary: Freeze on alt+f4 press
           Product: konsole
           Version: 15.08.0
          Platform: Debian testing
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: vbocek at gmail.com

Application: konsole (15.08.0)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- What I was doing when the application crashed:
I accidentally pressed alt+f4, a "confirm close" dialog showed up, and konsole
freezed, before the dialog even drew its contents.

This does not happen every time, typically after several hours of work when you
really don't wanna have to kill the Konsole. I usually have at least two
windows at a time open, too.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
