Description Patrick Silva 2020-09-11 13:55:04 UTC 
Application: plasma-discover (5.19.80)

Qt Version: 5.15.0
Frameworks Version: 5.74.0
Operating System: Linux 5.4.0-47-generic x86_64
Windowing system: Wayland
Distribution: KDE neon Unstable Edition

-- Information about the crash:
- What I was doing when the application crashed:
I opened Discover, some updates for widgets from KDE Store and for normal packages from neon repos were available.
I unchecked all widgets updates in "Update" page, clicked on "Update selected" button, canceled the password dialog (now all updates were selected again), clicked on "Update selected" button again, canceled the password dialog again and then Discover crashed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
