Bug ID: 368017
Summary: system setting crashes when assigning same shorcut to
two actions
Product: systemsettings
Version: 5.6.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: koz...@kufr.cz
Application: systemsettings5 (5.6.5)
Qt Version: 5.5.1
Frameworks Version: 5.23.0
Operating System: Linux 4.4.0-36-generic x86_64
Distribution: Ubuntu 16.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I have assigned Meta+M key shortcut for window maximize action.
Then I have assigned the same shorcut for window minimize action.
I got a dialog asking me whether I want to reassign the shorcut to new action.
I have confirmed it and the system settings has crashed.
The crash can be reproduced every time.
