Summary: sys.setprofile()  coredumps

Initial Comment:
Verified in current CVS (also on Windows, but doubt 
the platform matters).  It's not the call proper that 
coredumps, but an eval loop's later attempt to use a 
resulting NULL pointer.  From c.l.py:

Subject: minor Python bugs

Calling sys.setprofile() (with no args) makes the 
interpreter crash, and calling sys.settrace() with no 
args succeeds, even though it is documented to take 1 
arg (tracefunc).

And yes, my version is '2.2 (#28, Dec 21 2001, 
12:21:22) [MSC 32 bit (Intel)]'

I didn't read the part that settrace was a problem.
I can take a look at the settrace problem later.

It appears that this patches deals only with the setprofile
problem, not with the settrace problem. Is that intentional?
