Some possibilities:

* You are using a version of Python earlier than 1.6; previous to 1.6, 
int() took one and only one argument.  If this is the case, you can use 
string.atoi with the same interface.

* You are passing in an integer rather than a string(414243 rather than 
'414243'), in which case len(hex) will fail because an integer is an 
unsized object.

* You are not creating an instance of ConversionHandler and passing the 
argument to the instance to perform the work.  (Why are you making it an 
object method, anyhow?)
