I'm surprised that isn't having any effect. The Cairo backend should
not be running any code in backend_ps.py -- where the source of the
error is. If you put "backend: GtkCairo" in your matplotlibrc, does
that work?
What version of matplotlib are you running?

I don't think these settings will resolve the problem -- either font
type (42 or 3) still expects glyph names.
