Description Janne Mareike Koschinski 2020-10-31 15:30:02 UTC 
Application: plasmashell (5.20.2)

Qt Version: 5.15.0
Frameworks Version: 5.75.0
Operating System: Linux 5.4.0-52-generic x86_64
Windowing system: Wayland

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

The crash occured when logging in, when editing any widget or panel, or often as well when using the dashboard launcher. The crash deos not always occur, but it occurs on every login, and almost every time when trying to reorder widgets in panels, on the desktop, or items in the dashboard launcher (usually during the drag start or drag end a crash occurs).

- Unusual behavior I noticed:

Complete crash of plasmashell

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
