have you tried gdb python and then run with your_python_prog.py as the arg?
If gdb will catch a ctl-c then you might be able to use bt to get a backtrace?
(I don't really know much about gdb, but someone here has probably done this
and can tell you the right way to do it ;-)

Of course, there's the lions-in-africa thing of putting print statements to
narrow down successively the area where it could be hanging ;-)
