This is likely coming from the Proxy script you're using, so you'd have to look
into that. Possibly the server you're using is unable to open connections to
the URL in question. (Look in firebug to see the real underlying URL.)

Sometimes this happens when the server is running under SELinux, or other
permission restriction schemes; in any case, the problem is only going to
be something that you'll debug by looking at what the proxy script sees.
First step would be to get access from the same machine that the proxy is
running on, then to move into Python, then to finally move into Python-under-
Apache and see if there is anything weird at that level.

Good luck.
