Crash on OS X when running monoKickStarter

[dellis1972]

When running a sample OpenTK app under the monoKickStarter (https://github.com/OutOfOrder/MonoKickstart) project we get the following exception.

An exception was thrown by the type initializer for OpenTK.Platform.MacOS.NSApplication

Culprit is objc_getClass("NSAutoreleasepool") is returning NULL. http://stackoverflow.com/questions/11319170/c-as-principal-class-or-a-cocoa-app-without-objc suggests that there does need to be some special linking to get the foundation classes registered and initialized, so this looks like it might be a Kickstart issue.

[tomrijnbeek]

If I am correct, the current develop of MonoKickstart uses a pretty outdated version of Mono (2.*). There is currently a 3.12 branch that has an updated mono version, but it runs into a different problem for OSX (OutOfOrder/MonoKickstart#2), which also seems to be related to linking to certain foundation classes, so this might be a more general problem with using foundation classes in MonoKickstart applications.

Closing as this seems to be an an ancient upstream bug in a wierd configuration.
