Bug 357862

Application: systemsettings5 (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.1.13-5-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
I changed the shortcut "print" to launch spectacle. I guess I also tried to press the key after applying the change. Then systemsettings crashed.

This bug is probably a duplicate of bug 346335. However drkonqi did not allow me to add this information to the bug report or suggest this bug as a duplicate (probably due to bug 356822).
