Help in solving a segfault problem?

Hi all,
I am stuck on matplotlib generating a segfault when invoking 'plot'.
I've ben trying to solve this problem for a while now but no luck.
I've seen many duplicates of this problem on the web, some with
solutions, some without. The solution must be something more generic
that I'm missing.

Here are some of these pointers to the same problem that I have (the
backtrace, that I pasted further below, has the same properties)
http://old.nabble.com/101-Point-Segmentation-Fault-td27552745.html
http://old.nabble.com/weird-error-with-gcc-4.4,-gomp,-cython,-and-matplotlib-td27351399.html
http://bugs.gentoo.org/show_bug.cgi?id=338513

So here's my specific setup and backtrace. I hope I can find some help!
I'm using the 'agg' backend that's it, and the build and install dir
were cleaned up.

Thanks so much!

Hi,
I didn't get much reply on this issue, so I'm just trying to resurrect
the question.
If there's no easy answer, could someone help me by giving me a
pointer, a method to resolve the problem, or any other quick
advice...?

Thanks much!
