Application: plasmashell (5.14.5)

Qt Version: 5.12.0
Frameworks Version: 5.54.0
Operating System: Linux 4.14.98-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was connecting a second monitor when KDE failed, it's the first time I've happened.

- Unusual behavior I noticed:
There was lag in the system as soon as I tried to change the configuration to use the second monitor.

--I select arch linux but it really is manjaro linux (it was not in the list)

The crash can be reproduced sometimes.

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