[Matplotlib-users] Issues with PNG creation

[Benjamin Welton]

Hello All,

    Iv run into a strange issue involving outputting a graph to a png 
format. Anytime i try to output a png file the python interpreter 
crashes.  However when using other formats (such as pdf or svg) there 
are no issues with the output. I am running python 2.5.4 x86 on Windows 
2008 Server x64 sp1. I have included the error information and some 
short examples of code that i am attempting to use to output the data to 
an image format below. Any help i could get with this would be great.

Thanks,
Ben

Works Fine

 >>> import matplotlib   
 >>> matplotlib.use("Agg")
 >>> import pylab
 >>> pylab.plot([0,1,2,3],[0,1,2,3])
[<matplotlib.lines.Line2D object at 0x03228C10>]
 >>> pylab.savefig("test.svg")

Fails with crash error below
