Sentry Crash Report:

Description Méven Car 2019-03-04 11:09:27 UTC 
Application: plasmashell (5.15.1)

Qt Version: 5.11.1
Frameworks Version: 5.54.0
Operating System: Linux 4.18.0-15-generic x86_64
Distribution: Ubuntu 18.10

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

I have two screens, each with a plasma dashboard on it.
I was removing a plasma dashboard from the right screen.
Notice I probably added this dashboard under X window system.

- Unusual behavior I noticed:

Plasma crashed : the other dashboard dissappeared and windows covered its area.
Plasma then restarted showing correctly only the dashboard on the left screen.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
