Clock widget hangup

If you are very annoyed by system hangup when you have clicked clock widget to watch calendar or whatever in your Ubuntu 10.10 I can advise to do the following:

sudo apt-get purge evolution-data-server evolution-couchdb evolution evolution-exchange

That's all. After this you are avoided such unpleasant behavior.
It, however, removes Evolution mail client but if you don't use it as me that is not a problem.
