Sentry Crash Report:

Description ilochab 2018-05-08 15:30:07 UTC 
Application: plasmashell (5.10.5)

Qt Version: 5.9.4
Frameworks Version: 5.44.0
Operating System: Linux 4.15.17-200.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

-- Information about the crash:
- What I was doing when the application crashed:
I was typing in the search area of "Avviatore delle applicazioni" (applications launcher), but the some things happens even if I start typing in the KRunner window

- Unusual behavior I noticed:
The compleete desktop becomes black but the applications' windows survive. After few seconds the tesktop is restored. If I repeate the typing the time to restore the desktop after its desappearance encreeses.

The crash can be reproduced every time.

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