Application: plasmashell (5.12.90)

Qt Version: 5.11.0
Frameworks Version: 5.47.0
Operating System: Linux 4.18.0-0.rc0.git2.1.fc29.x86_64 x86_64
Distribution: "Fedora release 29 (Rawhide)"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to change desktop background with context menu; plasma freezes for a while, then back to normal after a few seconds
- Unusual behavior I noticed:
Previous version of plasma crashed the same way; this version is far better but something doesn't work with context menu (desktop settings)
- Custom settings of the application:
Custom icon set, custom background image

The crash can be reproduced sometimes.

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