Application: plasmashell (5.12.2)

Qt Version: 5.10.0
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
- What I was doing when the application crashed:
Starting the computer and loging in through SDDM.

- Unusual behavior I noticed:
The last few times I've booted my computer, plasma seems to crash right when it tries to start. Adding about ten seconds to the startup time. Seems to happen every time I boot my computer.

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".
