bpy's __rna__ attribute doesnt work as it should, since the parent classes __rna__ overrides the subtypes.

Browse Source 
For now have pyrna_struct_as_srna look in the dict first for __rna__ before using PyDict_GetItemString.
Somehow __rna__ is not calling the pyrna_struct_getattro function, python find it first.

The only relyable way to get the rna from python currently is.
bpy.types.SomeType.__dict__['__rna__']
