I see advice on how to debug a python module that hangs up the process

[Gustavo Campanelli]

I'm still newbie at Python, but not at programing, so this is just a 
wild guess. Have you checked that you are not using a reserved word as 
function or parameter name?
If the function hangs when it's invoked, are you using some Object as 
part of the call? Have you checked that object?
