Gnome problem when plotting with mpl

Hi,

a problem that I have since some time now using mpl: everytime I start
plotting, I get something like:

(python:6374): GnomePrintCupsPlugin-WARNING **: iconv does not support
ppd character encoding: ISOLatin1, trying CSISOLatin1

I know this is not really a mpl problem, but if anybody has a clue, it
is welcome!

cheers
Eric
