Bug 370916

Application: plasmashell (5.8.1)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.7.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed: I had just logged in. I did not try to open anything yet.

- Unusual behavior I noticed: I have a triple monitor setup. The monitor on the right was displaying a black background instead of the wallpaper I had selected. I could move the mouse cursor to this screen and still see the cursor. Plasma crashed about this time.

- Custom settings of the application: I am using the supplied Arch Linux packages. I run updates once a week. I have a triple monitor setup and an NVidia graphics card with the proprietary driver installed from the Arch repository.

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