matplotlib.tests.test_mathtext.mathfont_cm_23_test.test makes python debug to crash

[sandrotosi]

Hello,
when running unittests suite with python in debug flavor (pythonx.y-dbg in a Debian based distro) the interpreter crashes:

matplotlib.tests.test_mathtext.mathfont_cm_23_test.test ... python2.6-dbg: CXX/Python2/cxx_extensions.cxx:1320: virtual Py::PythonExtensionBase::~PythonExtensionBase(): Assertion `ob_refcnt == 0' failed.

and

matplotlib.tests.test_mathtext.mathfont_cm_23_test.test ... python2.7-dbg: CXX/Python2/cxx_extensions.cxx:1320: virtual Py::PythonExtensionBase::~PythonExtensionBase(): Assertion `ob_refcnt == 0' failed.

This is 1.2.0rc2 on Debian unstable machine.

I've hit it too with:
Python 2.7.3 (default, May 10 2012, 21:57:44)
[GCC 4.6.3] on linux2
