[matplotlib-devel] trunk rev 8843 crash on Snow Leopard

I built a binary installer for matplotlib trunk rev 8843 (because it 
leaks memory less than 1.0.0 release). I built it the same way I built 
the 1.0.0 binary 
<http://www.astro.washington.edu/users/rowen/BuildingMatplotlibForMac.htm
l> on Mac OS X 10.4 using python.org Python 2.6.x (where x is probably 
6).

The binary is available here:
<http://www.astro.washington.edu/users/rowen/python/matplotlib-1.0.0+svn8
843-python.org-py2.6-macosx10.3.dmg>

It work fine on Mac OS X 10.4 and 10.5, but on 10.6 attempting to import 
pylab almost always segfaults (and the few times I've gotten it to work 
on 10.6 I can break it by deleting ~/.fontconfig and ~/.matplotlib and 
running Python again). I've tried it on newly created accounts and it 
segfaults. Another user of Snow Leopard first reported the problem. So 
it's not just me.

I've appended part of a crash log.

I built this binary the same way I built the matplotlib 1.0.0 binary, 
which has no problems.

Any ideas?
