This looks like an Ubuntu problem to me. Unfortunately, I don't know where to 
report this problem.

Just a guess,but any chance you upgraded Ubuntu from 10.10 to 11.04, but 
haven't updated your installed packages?

(1) System -> Administration -> Update Manager
(2) Click [Check]
(3) Click [Install Packages]
