no traceback??

[Rainy]

Hello,

My program (http://silmarill.org/cymbaline/cymbaline/cymbaline.py - yes, 
it's repeated 3 times, that's not an error) works fine in 2.1 but exits
silently in 2.0 - no traceback, no errors, nothing. One possibility I checked
for is except (something): sys.exit() and I don't have anything like that here.
What else could it be?
