Yeah, that's what I understood to be the case. However, coming in over
xmlrpc, I don't have any keyword arguments - I say that because that's
explicitly what I'm doing, but I'm not sure xmlrpc handles keyword args
anyway. The **kw is just there for easier use when the method is called
directly from zope.

I guess I could try, but I'm not convinced this is my problem at the moment.

>From what I can tell, the problem seems to be at line 58 (mapply.py):
Given a call signature like:
def method(self, *args, **kw)
c.co_argcount == 1
c.co_varnames == ('self', 'args', 'kw')
Now, 'names' (the variable) becomes only 'self' (the string) on line 58.
In this way, mapply.py seems to ignore the fact that I want my method to
accept an arbitrary number of arguments (line 69).
I don't know if there's a good reason for this, or whether I'm doing
things wrong. I also don't know why this only crops up over xmlrpc, as I
presume mapply.py is used (in some way) from within zope as well.
