What about doing exception kind of like a C switch statement with a 
default case:

try:
  do_something()
except TypeError:
  fix_something()
except:
  print "Unknown error, you are doomed"
  traceback.print_exc()  #something to print the traceback
  exit_gracefully()

Is this frowned upon?  You still handle the error and you know where it 
happened and what happened.  Anything wrong with this?  I don't like the 
idea of my system crashing for any reason.
