I assume you're using the matplotlib 0.91.2 that's distributed with Ubuntu 8.04.
There was a recent fix for segfaulting in the exact same place (outside of any sort of freezing apparatus). Since it was related to the interpretation of a pointer, it's possible that you would see this inside of cx-freeze and not outside on the same machine, just because things get loaded into different parts of memory. I would try that fix first, and then look at problems related to freezing. We should have a new release out shortly, but it's unclear how long that will take to trickle down into Ubuntu repositories. You can check out the SVN maintenance branch from here (which has this bugfix): svn co https://matplotlib.svn.sf.net/svnroot/matplotlib/branches/v0_91_maint matplotlib-0.91.x Let us know how that works for you.
