[Python-checkins] python/dist/src/Lib sets.py,1.31,1.32

Update of /cvsroot/python/python/dist/src/Lib
In directory usw-pr-cvs1:/tmp/cvs-serv11467

Modified Files:
	sets.py 
Log Message:
Closes SF bug #628246.

The _update method detected mutable elements by trapping TypeErrors.
Unfortunately, this masked useful TypeErrors raised by the iterable
itself.  For cases where it is possible for an iterable to raise 
a TypeError, the iterable is pre-converted to a list outside the
try/except so that any TypeErrors propagate through.
