I have found the location of the error, but have not yet determined how the 
problem arises:
Basically, when savefig() is called by the script, the first draw_rectangle() 
call fails an assert gc.OK() statement. I have not determined why Python is 
not receiving the AssertException - my conjecture is that the call to gc.Ok() 
is causing an exception in the C++ code - I will probably have to use a debug 
version of the wx libraries and a debugger to verify this.
The stack frame when the exception is raised is:
__main__ #40
matplotlib.matlab.savefig #798
matplotlib.backends.backend_wx #812
matplotlib.artist.draw #86
matplotlib.figure._draw #65
matplotlib.artist.draw #86
matplotlib.patches._draw #76
matplotlib.patches._derived_draw #154
matplotlib.backends.backend_wx #403
I'll let you know how I get on...

I haven't had a chance yet. Real job has been very busy, but that should
change soon. Sorry about the delays.

The site came up late last night (for me). Today, I'm just going to import
files etc. I can look at install instructions and so on maybe tomorrow.
