Description magiblot 2018-06-06 10:58:27 UTC
Application: plasmashell (5.12.5)

Qt Version: 5.11.0
Frameworks Version: 5.46.0
Operating System: Linux 4.16.13-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

I was using two monitors. Desktop icons/shortcuts/items ('Home' and 'Trash', I don't know what technically they are) appeared in the screen I didn't want them to, so I tried dragging them from one screen to the other. A context menu appeared with some options, and I chose 'Move here', but it wouldn't work because plasma would attempt to overwrite the files in the 'Desktop' directory. I skipped overwriting.

Then I tried dragging them again and then chose 'Add Icon', under 'Widgets' in the context menu. However, this again was not what I wanted and I made right click on the icon > 'Remove this Icon', which sent it to the Trash.

Eventually, I thought of undoing all the movements I did, so I made right click on the desktop > 'Undo Move'. Then the desktop turned black and the task bar disappeared: Plasma had crashed. After some seconds, Plasma recovered and the icon I created with 'Add Icon' was there again, so the 'Move' action I undid was 'Remove this icon'.

Comment 4 magiblot 2020-12-19 21:07:48 UTC
Fixed. Dragging icons on the desktop no longer pops out a context menu, but effectively changes their position. So there is no way to reproduce the issue in Plasma 5.20.5.

Setting to RESOLVED > WORKSFORME because I have no clue when this was fixed.
