[issue10892] segfault with "del X.__abstractmethods__"

[Amaury Forgeot d'Arc]

New submission from Amaury Forgeot d'Arc <amauryfa at gmail.com>:

A short crasher::
    class X(object): pass
    del X.__abstractmethods__

All versions since 2.6 are affected.
The fix is probably simple: the setter function type_set_abstractmethods() in typeobject.c should check for a NULL value.
