Application: konsole (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.10.0-38-generic x86_64
Distribution: Linux Mint 18.3 Sylvia

-- Information about the crash:
- What I was doing when the application crashed:
I was closing the konsole application. It happens every now and then (perhaps 1 in 20 attempts).

- Custom settings of the application:
May or may not be related: I am using easystroke (mouse gesture recognition application) - the corresponding gesture is translated to the "Alt+F4" key shortcut.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
