Application: kwin_x11 (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 4.1.6 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- What I was doing when the application crashed:
starting the session after the computer freeze while sleeping.

It's possible that the package was upgraded since last time I logged in.

The crash can be reproduced every time.

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