[MonoDevelop] monodevelop fails to start

[Nicholas Frechette]

After realizing that the gtk sharp master branch was for gtk3+ and not
gtk2 which monodevelop uses, I had to manually apply the patch here
https://github.com/mono/gtk-sharp/commit/3862bc75ec60aed9589d16d177f0e6684c8cb6d7
to the lastest stable gtksharp 2.12.11 to get monodevelop to work. (I
just hacked Thread.cs locally)

This means that with the latest stable mono/gtk#/monodevelop all built
from sources in ubuntu 12.04 default install will not work for any
gtk2# applications.
