I admit that I was slightly trolling there, since Giuliano was 
complaining about exceptions that he wasn't seeing (because, it turns 
out, he wasn't catching them).

However I feel that my point stands: if the program opens, checks and 
closes the .ini file before the main logic starts, then it's possible to 
keep those initial activities separate from any try-finally required by 
the application logic. This initial activity obviously still requires 
both a try-finally and a try-except, which is where he was going wrong 
with his initial attempt.
