I found Fabio's example very handy so I made it into a module and used 
the pretty printer instead of print:

FWIW, here is my excepthooker.py file:

"""
Print locals and globals on any exception.

Usage:
import sys
from excepthooker import myHook
...
if __name__ == '__main__':
     sys.excepthook = myHook
...

"""

import sys
import pprint


def myHook(type, value, traceback):
     ppr = pprint.PrettyPrinter(indent=4)
     initial_ctx = traceback.tb_next
     while initial_ctx.tb_next is not None:
         initial_ctx = initial_ctx.tb_next
     print 'locals on exception:'
     ppr.pprint(initial_ctx.tb_frame.f_locals)
     print 'globals on exception:'
     ppr.pprint(initial_ctx.tb_frame.f_globals)
     #now, call the original.
     sys.__excepthook__(type, value, traceback)

# Testing code follows
