Sorry, I forgot to mention that this test failed on 64-bit Python 2.6 
only. I now recognize it is due to a known issue with Python's 
PyErr_Format function <http://bugs.python.org/issue7228>. Unfortunately 
the fix will not be backported to Python 2.6. Maybe this test could be 
marked as known failure on win-amd64-py2.6?

Could you please revert your changes or set the format specifier to 
"%lld"? "%I64d" is not supported by PyErr_Format.

Thanks,

Christoph
