You might try using runcall() instead. I'm not really familiar with
what cProfile may be doing in runctx() that will make it try to use
objects in the namespace as keys in a dict.
You may want to take a look at my kernprof.py script which is a useful
driver script for profiling any Python script without your having to
bother with making your own driver script.
