During handling of the above exception, another exception occurred:

What I forgot to say is that the test was launched from the C: drive:

C:\>z:PCbuild\python_d.exe z:Lib\test\regrtest.py -uall -v test_urllib2

I no longer have a 2.7 setup so can someone else try to reproduce this problem.

This was fixed under issue7648.
