Hi:
I obtain the following error when saving a figure to postscript after
running one of the test routines in mplot3d.py:
>>> from numpy import *; import mpl3d.mplot3d as p3; import pylab as p
>>> p3.test1()
>>> p.savefig('test1')
Traceback (most recent call last):

AttributeError: TextWithDash instance has no attribute '_mytext'
I installed matplotlib-0.87.3 and mpl3d yesterday and today. After a
bit of hunting, I noticed there are two similar definitions of
TextWithDash in matplotlib's text.py: _TextWithDash and TextWithDash.
Noting the underscored version defines _mytext but the underscore-free
version does not, I switched the underscores. Now things are working
(though perhaps I've broken something else in the process). I suspect
the error is a product of on-going changes to matplotlib; nonetheless,
I thought my email might be helpful to others.
