Python Win32 bindings broken ? (Was Re: Getting better error messages out of the Python bindings)

Hi !

I have a problem with the Subversion Python Win32 bindings. The gist of
it is that I can't get any useful error messages out of Subversion's
libraries.

cmpilato was gracious enough to offer me some help, earlier on, but he
was using Linux, and he had no Win32 box to use.

If someone with Win32 could try the following script, or cmpilato's
modified one, I would be grateful. This problem is preventing me from
continuing on developing RSVN, at the moment. If the problem can be
found, then I'll be fine from here on.

BTW, this problem is not specific to me:

Thanks !
François
