I get the same "SystemError: null argument to internal routine" error. I have seen the same error for commands other than svn_repos_open. It's a common response to invalid values.

Subject: 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
