Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv4146

Modified Files:
	test_descr.py 
Log Message:
Fix for SF bug 551412.  When _PyType_Lookup() is called on a type
whose tp_mro hasn't been initialized, it would dump core.  Fix this by
checking for NULL and calling PyType_Ready().  Will fix this in 2.2.1
too.
