[Pythonmac-SIG] Strange python behavior after upgrading to OS X 10.5.3

[Larry Meyn]

I had the same problem on another Mac just upgraded to 10.5.3 from  
10.5.2. This time the traceback was a little more helpful and the  
error occurred after opening a .pyc file.  The solution was to delete  
all the .pyc files used and the newly regenerated ones worked fine.
