[python-win32] problems with subprocess module and env parameter

[Preston Landers]

Your PATH is a Unicode string.  I'm not sure offhand if that's acceptable or
not, but all the rest of the strings appear to be regular (non-unicode)
strings.

You could also try:

import types
for k, v in env.iteritems():
    if type(v) is not types.StringType:  print k, v

hope this helps,
