Another possible source of this error, considering the 
implementation of string.split(), is that you're actually passing 
in a None as the argument.  The code for string.split() is 
basically this:

### in module string.py ###
def split(s):
    return s.split()

Of course, if you're running into this problem with anything 
other than string methods, or if it happens when you pass 
something that you *know* is a string, then this isn't the 
problem, and odds are that you're shadowing your global module 
names, as everyone else is suggesting.  :)
