Application: plasmashell (5.4.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04

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

I was trying to add a plasmoid when this crash happened. Plasma 5.4 from Kubuntu CI PPA. There are other problems with the system, but the crash happens every time.

The crash can be reproduced every time.

-- Backtrace:

What menu is open?

You said this happens every time.
Could you please give steps of what *exactly* you did.

Created attachment 94293 [details]
Plasmoids are not working as well

1. Update Plasma 5.3 from backports to Plasma 5.4 from CI. 
2. Restart computer.
3. Click on panel settings, click "Add Widgets...".

Then the crash happens. It is possible that something is wrong with my config after update. I removed all .kde, .local and .config from my home directory without any luck. Some of the plasmoids in the panel do not work (even after adding new default panel). Maybe this is the reason for this crash?

Comment 3 David Edmundson 2015-08-30 20:52:58 UTC

That error means some files are missing.

Please talk to the Kubuntu people
