Application: plasmashell (5.7.0)

Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.6.4-2-default x86_64
Distribution: "openSUSE Tumbleweed (20160625) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
When I login, my dual display configuration from the last login session doesn't load. The second display is enabled, and I can see my mouse cursor on it, but nothing else displays (no wallpaper, no widgets, etc). When I go about re-applying my display configuration, plasmashell segfaults.

- Unusual behavior I noticed:
My dual display configuration (span across screens) does not appear to be preserved or saved when I logout or reboot and must be re-configured at every login. This started with the upgrade to Plasma 5.7. Stock Tumbleweed packages.

The crash can be reproduced sometimes.

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