Fix for SF bug 528132 (Armin Rigo): classmethod().__get__() segfault The proper fix is not quite what was submitted; it's really better to take the class of the object passed rather than calling PyMethod_New with NULL pointer args, because that can then cause other core dumps later. I also added a testcase for the fix to classmethods() in test_descr.py. I've already applied this to the 2.2 branch.
