Bug 365896

Application: kwin_x11 (5.7.1)

Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.7.0-desktop-0.rc7.6.mga6 x86_64
Distribution: "Mageia 6"

-- Information about the crash:
- What I was doing when the application crashed:
launching chromium for the first time in the session, a previous tab needs to restore login informations, so wallet window appears, and Kwin crashes.

It seems that having firefox already running before launching chromium is needed.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
