This was good, the actual error; I suspect you overwrote IndexError.
The general principal is to boil down your code to the smallest code
that exhibits the problem.  This is not just to aid us, since usually
at some point you delete a block of lines and the problem goes
magically away.

More points for identifying Python version and OS.

As above, but to test my theory:

...
     except Exception, e:
         print 'caught %r: %r (IndexError is %r)' % (
                      e, e.__class__, IndexError)
