It looks like someone is calling a function with a string, but the 
function is expecting a sequence of strings.  Three cheers for string

This is definitely a bug in Twisted somewhere, so you should go to 
http://twistedmatrix.com/bugs/ and report the issue.  Though, you may 
want to do a search first; the problem may already be solved in CVS.
