This seems to have solved the problem on the two systems on which I've
run experiments. Now it makes perfect sense why I was always seeing a
corrupt file size that was a multiple of 4K (e.g., 12K instead of 13K) :) .
So just to confirm, is this a bug in matplotlib when using the
plt.savefig(filename,dpi=72) form of calling savefig?
Thanks,
