Comment 1 for bug 1185231

I tested the basic behaviour on 2.6:
cat /tmp/t.py
raise AssertionError
python /tmp/t.py
Traceback (most recent call last):
  File "/tmp/t.py", line 1, in <module>
    raise AssertionError
AssertionError
robertc@subunit-lucid:~$ echo $?
1

so something has broken your Python 2.6 behaviour w.r.t. exception handling.
