[Python-modules-team] Bug#505527: python-matplotlib: PS and EPS backends fail

[Borja Bergua Guerra]

Package: python-matplotlib
Version: 0.98.1-1+lenny3
Severity: important

When I try to save a figure to a PS or EPS file, I get an error.
This is a very simple piece of code that generates the error:

#!/usr/bin/env python
"""
Example: simple line plot.
Show how to make and save a simple line plot with labels, title and grid
"""
import numpy
import pylab

t = numpy.arange(0.0, 1.0+0.01, 0.01)
s = numpy.cos(2*2*numpy.pi*t)
pylab.plot(t, s)

pylab.xlabel('time (s)')
pylab.ylabel('voltage (mV)')
pylab.title('About as simple as it gets, folks')
pylab.grid(True)
pylab.savefig('simple_plot.eps')

pylab.show()

When I execute the above program what I obtain is:

$ ./cos.py
Traceback (most recent call last):
