Application: plasmashell (5.11.1)

Qt Version: 5.9.1
Frameworks Version: 5.39.0
Operating System: Linux 4.13.0+ x86_64
Distribution: KDE neon User Edition 5.11

-- Information about the crash:
- Unusual behavior I noticed:

Plasma shell will crash when the system is locked or it will crash when I 'm using the system.  Sometimes it will restart on it's own but I usually restart it by hitting Alt-F2 and typing in "kstart5 plasmashell"

The crash can be reproduced sometimes.

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