[matplotlib-devel] Problem in backporting Matplotlib for Py3 on Kubuntu Precise

[Shriramana S. <sa...@gm...>]

Hello. I don't use Matplotlib directly (yet) but I wish to use
https://github.com/scios/IPyXt which needs it, and I'm using IPython
and SymPy both with Python 3. (Current version on my Kubuntu Precise
system is 3.2.3.) So I'm trying to backport v1.2.0 from Kubuntu 13.0x
(http://packages.ubuntu.com/raring/python3-matplotlib). I have all the
build-dependencies (I backported python3-dateutil and python3-tz too
from latest Debian) but when I run dpkg-buildpackage, it terminates
with the errors:

python-dbg: ../Objects/object.c:65: _Py_AddToAllObjects: Assertion
`(op->_ob_prev == ((void *)0)) == (op->_ob_next == ((void *)0))'
failed.
Aborted (core dumped)
make: *** [clean] Error 134
dpkg-buildpackage: error: fakeroot debian/rules clean gave error exit status 2

The complete runlog is attached. Can anyone please help me out? Thanks.
