transfrom.frozen() failing on account of matplotlib.nxutils

[Horea Christian]

Hey there, this question is rather matplotlib-oriented but they don't seem to have a working user mailing list.

I am using psychopy ( a python lib depending on scipy, numpy, and matplotlib), and I am having the following issue https://groups.google.com/forum/?fromgroups=#!topic/psychopy-users/1L1U-VZwXZc

In short my error message is http://paste2.org/p/2753557

I have been told this is due to how matplotlib.nxutils is working on my system. I am running matplotlib-1.2.0-r1

Could you give me any pointers regarding this?

Cheers,
