Hello!
I'm trying to plot a function using Sage-5.3 on Debian Wheezy
(testing) and I get the following error message:
Value error parsing header in AFM: ItalicAngle -10,5
Traceback (most recent call last):

It seems strange, because I also use Sage-5.3 on a couple of other systems
(Gentoo and Ubuntu), but have never experiences such problem, and Sage is
compiled in a separate directory as you can see (/opt/sage-5.3), which makes in
system-independent, doesn't it?
