On my computer at home I never user a dedicated email client (Thunderbird in 11.10) and therefore wanted to remove the entry in the Message Indicator. I also have an aversion against Gwibber so that had to go as well. Normally I just remove the applications from the computer, but in 11.10 you can't remove Gwibber without removing the entiry ubuntu desktop (WTF?). Anyway I finally found this post explaining how to do it.
Unfortunately it didn't work for me, so I removed the entries instead of blacklisting them like this:

$ rm /usr/share/indicators/messages/applications/thunderbird
$ rm /usr/share/indicators/messages/applications/gwibber.indicator
After logging out and back in, the entries was gone. Excellent!
