This error is still present in Ubuntu Oneiric, but for mono applications
created with monodevelop and using Gtk#, but for some reason not for
applications bundled with the operating system.

The same happened to me in Windows, and the problem disappeared
upgrading to the current version of Mono (2.10.6). I guess this is going
to be the same thing.

Unfortunately, recompiling applications is not an option, as Monodevelop
2.6 is unable to find the Gtk# in the system (?). Again, the same
happened to me in Windows, and upgrading to the current version (2.8)
solved the problem.

Would it be possible to upgrade these packages to their current versions, so this bugs disappear?
If not, how can I solve this in my system, so I'm able to use mono again?
