My Mac begs to differ:

~ $ cat Desktop/tmp.py
def test():
   raise AssertionError

try:
   test()
except AssertionError:
   print "caught AssertionError"
~ $ /System/Library/Frameworks/Python.framework/Versions/2.5/bin/python2.5
Desktop/tmp.py
caught AssertionError
~ $ /System/Library/Frameworks/Python.framework/Versions/2.5/bin/python2.5
Python 2.5.1 (r251:54863, Feb  4 2008, 21:48:13)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin

The problem must lie elsewhere.

Cheers,
Chris
