I'm using kubuntu 15.04. All of a sudden (without doing an upgrade), when I log in, my plasma does not start. I am in the desktop with my applications open, but no panels, no menu, no background.
sudo plasmashell works (but as a root), not as a normal user. I'll try upgrading now, but I'm a bit worried I should fix this first. Maybe I should check a particular log?
Could this be a permissions problem? I've been using Dolphin as a root to solve a backup problem's write permissions, maybe that was a bad idea.
--UPDATE
I changed the ownership of all files in /home/me to myself. Afterwards, trying to run plasmashell:

I did recently set my DL_LIBRARY_PATH variable in .bashrc. Could that be interfering? (looking at this bugreport)
-- UPDATE2
I've created a new user. Plasma works perfect for that user. It's a bit annoying to have to do all my desktop settings again, but ok... I'm guessing it was a permission problem then? No clue...
