Which version of gnome-print you are using?
Leak is known libart bug, but latest gnome-prints try to overcome that
by perturbing vpaths.

Use gnome_print_master_preview. Although not ideal, it allows a little
bit more flexibility.

You can get font names with gnome_font_list and family names with
gnome_font_family_list methods.
Fonts usable are defined in $datadir/fonts/fontmap(2) file. Gnome-print
tries to find fonts installed on your system, but may fail, in whihc 
case may not have std. postScript fonts available.
If you compile gnome-print by hand, try:

tests/testprint4 --preview some_text_file_name

It shows you font dialog, where you can examine available fonts. If 
there is no Helvetica, times and such, fontmap installation went wrong.

Symbol shows empty squares most probably because gnome-print expects
utf-8 strings. Adobe has allocated unicode values for all glyphs in
both Symbol and Dingbats fonts, so you have to encode those into
utf-8.
