BUG: profile.py

[Jon Travis]

There is a small bug while running some of
the profiling code from within the profiler.  
Specifically:

import profile
x = profile.Profile()
x.run("x.dump_stats('/tmp/foo')")

I have a small 2 liner fix, but I doubt it is correct,
merely a band-aid, so I won't post it.
