Operating System: Linux 4.14.15-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
    I did login from SDDM with Plasma. Then plasma welcome screen appeared, when finished loading plasma was crashed but kwin and krunner were still active. I've started plasma from krunner and it's working properly

The crash can be reproduced sometimes.

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