Operating System: Linux 4.0.0-0.rc5.git4.1.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
$subject

- Unusual behavior I noticed:
it crashed even when disabling the non-primary screen, but this may just be a dupe of the other one.

- Custom settings of the application:
F22 updated, dual head, laptop screen plus another screen on DP.

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