-- Information about the crash:
- What I was doing when the application crashed:
This time plasma crashed when I edited the task bar.

- Unusual behavior I noticed:
It is overall very slow (my pc isn't, was running kubuntu previously everything was fine)
Often freezes (At login, after a minute shows desktop, it's uninteractable, ater 5 more minutes it shows the task bar ; 
	Sometimes when searching something)
Kde applications apper, but sometimes it takes them 3 minutes to be interactable.

I had the same issue on gentoo yesterday,

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
