Application: plasmashell (5.10.2)

Qt Version: 5.9.0
Frameworks Version: 5.34.0
Operating System: Linux 4.11.6-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
Plasma sometimes crashes when I'm manipulating with plasmoids. It usually crashes after some action (widget is added, removed, ...). The desired action is finished correctly, but the crash is bit annoying.

The crash can be reproduced sometimes.

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