Yes, it fails even with the simple plot suggested; see log below. I am new
to Python but I did also try inserting the command:
print rgb 
preceding the offending line, to get an idea of what the dimensions of 'rgb'
are but the print statement also fails due to 'too many values to unpack'

savefig("foobar.emf")
