Summary: PyErr_WriteUnraisable lacks exception type check

Initial Comment:
I'd hit an access violation inside PyErr_WriteUnraisable when a non-exception 
instance was raised. The call to PyExceptionClass_Name with a non-exception 
instance is yielding an invalid pointer.
I'd hit the bug embedding Python 2.5 and raising a string instance via 
PyThreadState_SetAsyncExc but I could also reproduce the crash with this sample 
code:

class Foo:
    def __del__(self):
        raise "pum"

a = Foo()

Thanks for the report.  The print is kinda crappy, but it shouldn't
crash.
