Application: plasmashell (5.4.2)

Qt Version: 5.5.0
Operating System: Linux 4.2.3-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
When logging into a 3 monitor configuration plasma is only running on one monitor, even though the other two monitors are active. They are also part of the session as I can move windows to the screens. I entered system configuration>screen, and disables the two extra monitors , applying changes.
I the reenable the two extra monitors, applying changes. After this plasma crashes.

The crash can be reproduced every time.

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