Description Mayeul C. 2019-02-16 18:21:39 UTC

Application: plasmashell (5.15.0)

Qt Version: 5.12.1
Frameworks Version: 5.55.0
Operating System: Linux 4.20.8-arch1-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
 - right clicked on the desktop -> add default panel

I find plasmashell on wayland to be quite unstable. It crashed again a few minutes later when I right clicked on a kickoff icon.

kwin tends to crash as well, especially when my mouse moves from one screen to another. Unfortunately, drkonqui doesn't always show up when I hit those crashes.

The crash does not seem to be reproducible.

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

All right, I found out shortly after that it might be related to my having only one virtual desktop after deleting some config files.

Unfortunately, kwin messed up the screen, and I was in a hurry to post the crash report before restarting it, so I couldn't add that information to the original report. This seems to happen when switching TTYs.
