Bug 358558

Application: kwin_x11 (5.4.3)

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:
- What I was doing when the application crashed: I have logged into the system and after a while I was trying to open Dolphin. It has started to open and the screen has frozen. To make it responding I found useful to swich to another console and close the lid of my laptop. This results with system going to sleep. After it was waken up and swiched back to graphical console all actions were executed and finally I have seen the login screen. After login crash notification is displayed. This problem pops up not only during Dolphin start, but occurs with many other application.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
