Bug 359284

Application: kwin_x11 (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
In this particular situation I was trying to open Firefox. Unfortunately it does not matter what I do or did i happens quite offen. While I double click on any icon KDE crashes. It might be related to problem that I'm not able to change setting for my mouse/touchpad to use double click instead of one click on icons. Additionall I have no available settings panel for synaptics device on my account. On root account his settings are available, but also double click can't be enabled. I would really appreciate any help with this issue.

The crash can be reproduced every time.
