[Debian-science-sagemath] Sage broken with Python 2.7.13~rc1-1

[Tobias Hansen]

Actually it looks more related to https://bugs.python.org/issue24469

>From the changelog:
Issue #24469: Fixed memory leak caused by int subclasses without
overridden tp_free (e.g. C-inherited Cython classes).

And our error happens at tp_free in sage/misc/classcall_metaclass.pyx
