not when i try it... what do you mean by "hangs" does it takes forever or 
do you see an error message? if its the later, then you might have assigned 
something to "int" somewhere else, hiding the builtin function.

note that you should not use "str" as a name as that is a builtin 
object/function that can be very handy. e.g. in python 2.2+ you could have
written "details = str.split(line)"
(or even "details = line.split()" which i prefer)

also note that split() might not be safe for every case. e.g when the user 
name contains a space (if possible) and surely when the filename has a 
space in it.
