This may be due to my system running the latest software; gtk-sharp is already +4 years old of the last release. :(

But if someone may find some time in the future, it would be nice if gtk2 can remain supported. Note that pygobject,
ruby-gtk3, and most of the GNOME apps work fine on my system, so I doubt it is related to my system as such
and thus must be related to something within gtk-sharp. I am a noob when it comes to C/C++/C# though.
