I then receive a plasmashell crash with the following backtrace:


Sorry for taking so long in getting back to you. We had a flood of issues back 
in October 2015 related to the migration from qt 5.4 to 5.5, and kde 
frameworks upgrade to 5.15, and this was one was overlooked back then.


Can you test this issue again against the current versions of kde 
plasma-workspace?


I think that this issue might be related to one the previously mentioned 
changes.


Happy hacking,

Bug#802314: plasma-workspace: plasmashell crashes when adding widgets to desktop

[Vivia Nikolaidou]

Package: plasma-workspace
Version: 4:5.4.2-1
Severity: important

Dear Maintainer,

I want to add a widget (any widget) to my desktop, but when I try to do so,
plasmashell crashes.

Steps to reproduce:

1) Unlock widgets (if locked)
2) Right click the desktop
3) Select "Add widgets..."
4) Select a widget from the list that appears on the left side of the screen
5) Drag it to the desktop

I then receive a plasmashell crash with the following backtrace:
