Comment 1 Robby Engelmann 2014-03-31 15:40:30 UTC 
I guess milou was the problem here. I updated it and put its widget to the systemtray.
After removing milou all is starting smooth again.
Comment 2 Ignacio Serantes 2014-04-21 08:41:22 UTC 
Happens to me too. Solved editing plasma-desktoprc and removing Milou from System Tray.

New crash information added by DrKonqi

plasma-desktop (4.11.9) on KDE Platform 4.13.0 using Qt 4.8.6

- What I was doing when the application crashed:
Logging into the system

- Unusual behavior I noticed:
Plasma Desktop crashed

- Custom settings of the application:
I had recently added milou to the systemtray before the last logout

plasma-desktop (4.11.8) on KDE Platform 4.13.1 using Qt 4.8.5

- What I was doing when the application crashed:

Added Milou to the system tray and began experiencing these crashes. Can't seem to even start plasma-desktop from the terminal, I get an error.

Addendum:

I have/haven't had any Milou in the system tray.

But a new log (starting plasma-dektop in the konsole):
