Problem with XML-RPC: arguments->list in first argument

I've been having this extremely weird problem with XML-RPC.

Basically, when I call the function from within the php file, it works.
When I call it over XML-RPC (from python) the arguments are passed into
the function as a list in the first paramater, and the other arguments
are left blank.

The code can be seen here: (line 398)

Any ideas *what* the problem is? I could probably fix it if I knew what
the problem was. The other functions seem to work fine over xml-rpc.
