Reproducible: Always

Steps to Reproduce:
It happens every time I log in to KDE.

Actual Results:  
The tray icons aren't hiding and they are colorful (instead of mono). I can't log in to KDE Bug system via KDE Bug reporting tool, only with web browser. I can't acces the 'services' section of KDE settings. There are also some minor effects, I can't remember them all.

Expected Results:  
The kdeinit4 should start with every KDE start.
