Bug 402022

Application: plasmashell (5.14.4)
 (Compiled from sources)
Qt Version: 5.11.3
Frameworks Version: 5.53.0
Operating System: Linux 4.19.7-gentoo-pelo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
Nothing, pc with monitor in sleep, idle at all, loaded apps
ktorrent, teamviewer

- Unusual behavior I noticed:

Every time the sistem starts up and stays in idle, plasma hangs

The crash can be reproduced every time.

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