Bug 389288

Application: plasmashell (5.11.5)
 (Compiled from sources)
Qt Version: 5.9.3
Frameworks Version: 5.40.0
Operating System: Linux 4.14.14 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

I recompiled kde-plasma/kscreenlocker at a stable Gentoo Linux with and without -seccomp USE flag  to check whether it works now.
Maybe I looked into systray too.

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