The problem occurs only when I run the application through the debugger in MonoDevelop. If i don't add the OpenTK OpenGL control to the window the application runs.

The output looks like this (full stack trace in attachement problem.txt):
** (/Users/hannes/Projects/Revolutions2/Testing/bin/Debug/Testing.exe:1495): WARNING **: mono_class_from_mono_type: implement me 0x8b
