The lines in question look like:
	if (!MONO_CLASS_IS_INTERFACE (class)) {
		class->parent = parent;

		if (!parent)
			g_assert_not_reached (); /* FIXME */

This code looks like it is trying to initialize the parents of the class
being setup. Maybe you are inheriting from a new 2.0 class that we have
not created?

I'd first try compiling your program with gmcs. If there are classes
that we don't have, it should be more easily apparent there.
