Has this been resolved yet? I'm running Matplotlib 0.87.5-2.2 on
Debian Unstable. I try to run the following script:
from pylab import *
hist(rand(100), 20)
ax = gca()
ax.set_yscale('log')
show()
And get the error:
Traceback (most recent call last):
File "/usr/lib/python2.4/site-packages/matplotlib/backends/backend_gtk.py",
line 284, in expose_event
self._render_figure(self._pixmap, w, h)

tverts = self._transform.seq_xy_tups(verts)
ValueError: Domain error on nonlinear Transformation::seq_xy_tups
operator()(thisx, thisy)
The error is always reproducible, both from the console and the ipython console.
Any ideas?
