 Whoever looks at this bug, don't get confused by Miguel's last comment
 - it's not the assembly code which is wrong.

 I hate bugzilla for typing in a long comment and then eating it :-(

+Just look at the IL:
+
+    IL_0001:  newarr     [mscorlib]System.Byte
+    IL_0006:  call       void class X`1<uint8>::Y(class
+[mscorlib]System.Collections.Generic.IEnumerable`1<!0>)
+
+After the `newarr', there's an instance of System.Array on the stack.
+
+The `call' expects an instance of S.C.G.IEnumerable<T>.  Later on, the
+called method will make an indirect call through the vtable to call
+`GetEnumerator()' (or whatever) and this'll crash since it's using the
+wrong `MonoClass *'.
