"an error similar to this"?

Please post the actual traceback.

It would also help if you looked at the traceback for where your code 
calls the function from the stdlib and then added some debugging, such 
as to a log file, to see what you're passing to the function.

 From what you've provided above, it would appear to be a list, which 
appears to be the problem. Where does that list come from?
