Description Peter C. Trenholme 2018-05-06 22:24:30 UTC
Application: plasmashell (5.12.4)

Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.16.6-302.fc28.x86_64 x86_64
Distribution: "Fedora release 28 (Twenty Eight)"

-- Information about the crash:
- What I was doing when the application crashed: I was trying to change my wallpaper settings.

- Unusual behavior I noticed: For the last year or so my wallpaper setting have not been saved.

- When I started plasmashell in a browser window (The KDE display manager works fine, and I can start terminal windows, etc., with entries in .config/autostart.)

# I used this command to start the plasmashell:
$ plasmashell -n --desktopfile=/usr/share/applications/org.kde.plasmashell.desktop &
I noticed a lot of messages on the screen. (My added comment lines start with #.)

# It seemed to start out fine . . .

- Custom settings of the application: See above. They should be relatively default, since I just upgraded my system to Fedora 28. (Note: In the FR28 version on Rawhide, the plasmashell worked with no problem.

The crash can be reproduced every time.
