Small bugfix for gnome-font-picker

[Thomas Schultz <tststs gmx de>]

Hello,

I noticed that an application will crash if it calls
gnome_font_picker_set_font_name() with a string that does not contain a
certain number of dashes ("-"). I looked at the sources of libgnomeui and
found that this is due to a bug in gnome_font_picker_font_extract_attr()
which is quite easy to fix. The small patch is attached.

Thanks for your attention.

Kind regards,
    Thomas Schultz
