Version:           4.7 (using KDE 4.7.0) 
OS:                Linux

It started when I was in KOrganizer to manage my calendars.
I removed every calendars.
Then I added a first Google Calendar with iCal method. It worked great.
Then I added a second Google Calendar with iCal method too. Plasma desktop suddenly crashed.

I restarted my computer, after kdm, the plasma desktop starts good, loads my previous applications (not KOrganizer, I closed it before the reboot)
And plasma desktop crashes again.

After a few reboot (all of them made plasma crashed), I suspect maybe the systray calendar to crash the plasma desktop, because during the plasma startup, I can see the systray getting filled by battery, pastecut, Kopete successfully. And suddenly it crashes so it can be from there ?

Additional infos: When typing alt+F2 and launching plasma-desktop, it works without crashing. So it's only on booting/startup

Reproducible: Always

Steps to Reproduce:
Add 2 GOOGLE calendars (or more ?) to KOrganizer with iCal method.

Actual Results:  
Plasma Desktop should crash instantly and at every reboot.

Expected Results:  
Be a good boy.

I don't have custom widgets things or anything.

My only plasmoids are Weather, Picture, Color Picker, and System Watching (conky-like).
