It was a bad assumption. Not all exceptions are subclasses of 
"Exception". In this case, an inner call raised SystemExit(0). So be 
aware. Don't think that this will catch all exceptions:

try:
    ???
except Exception,e:
   do_with(e)


Use this instead:

import sys
try:
    ???
except:
   e = sys.exc_value
   do_with(e)
