Linux Mint 11: Clock indicator applet crashes randomly at startup

I have the same problem. Yesterday it was the clock applet. After I chose 'No' (don't delete from config) login, was fine, but the clock did not apppear. Today it seemed to be a general Appletindicator warning. I got these problems since this month. I had Mint 11 installled before.

It's like:
