I am using matplotlib-0.98.5.2 and getting a strange crash when trying to
show() a window with semilog or log-log axes. Here is a simple script that
will cause the crash:
import pylab
from numpy import *
x = arange(1., 10., 0.1)
y = x**2
pylab.semilogx(x,y)
pylab.show()
At the end of this message is a sample of the output. I had to cut it down
because it's apparently stuck in a loop in pyparsing.py and keeps outputting
the same repetitive message. Did I find a bug here? Any suggestions would be
appreciated.
