Bug 370652

Application: konsole (16.08.1)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.5-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

-- Information about the crash:
- What I was doing when the application crashed:
I was exiting the last Tmux window.

- Custom settings of the application:
I'm using this ~/.local/bin script called tmuxer in the command section of my usual Konsole profile:

#!/bin/sh
unalias
tmux -f ~/.config/tmux -2 att || tmux -f ~/.config/tmux -2
exit 0

This helps out opening existing tmux sessions or creating a new one if I haven't opened another windows yet.

Sometimes Konsole shows: [exit] but doesn't close its window, then a crash message shows up.

The crash can be reproduced sometimes.

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