Bug 381141

Application: kwin_x11 (5.10.1)

Qt Version: 5.7.1
Frameworks Version: 5.35.0
Operating System: Linux 4.10.0-22-generic x86_64
Distribution: Ubuntu 17.04

-- Information about the crash:
- What I was doing when the application crashed:

Clicked a chrome launcher in the plasma panel. Chrome launched normally and loaded tabs, but kwin crashed/restarted.

Kubuntu 17.04 up to date with current packages from the backports-landing ppa.

Package: kwin-x11                        
Version: 4:5.10.1-0ubuntu1~ubuntu17.04~ppa1

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