I can reproduce here on Gentoo, both with 0.99.3 and SVN trunk.
Trunk has the following warnings:
/home/rmay/.local/lib/python2.6/site-packages/matplotlib/axes.py:2305:
UserWarning: Attempting to set identical xmin==xmax results in
singular transformations; automatically expanding. xmin=0, xmax=0
warnings.warn('Attempting to set identical xmin==xmax results in
singular transformations; automatically expanding. xmin=%s,
xmax=%s'%(xmin, xmax))
/home/rmay/.local/lib/python2.6/site-packages/matplotlib/axes.py:2479:
UserWarning: Attempting to set identical ymin==ymax results in
singular transformations; automatically expanding. ymin=1.0, ymax=1.0
warnings.warn('Attempting to set identical ymin==ymax results in
singular transformations; automatically expanding. ymin=%s,
ymax=%s'%(ymin, ymax))
terminate called after throwing an instance of 'char const*'
So it doesn't seem completely odd that we have a crash here, but
should still be fixed (by someone who has a clue what might be going
on, which isn't me.)
