Application: plasmashell (5.10.5)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.0-42-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed: I was using Firefox when suddenly Plasma restarted, the crash only lasted two or three seconds. Widgets were not affected and the desktop was restored correctly.

- Unusual behavior I noticed: It did the same thing one or two days ago.

The crash can be reproduced sometimes.

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