gimp/libgimp/gimpvectors_pdb.c
Michael Natterer 6bca8c4f89 pdb, app, libgimp, plug-ins: replace most PDB filenames/URIs by GFile 
and in an attack of madness, changes almost all file plug-in
code to use GFile instead of filenames, which means passing
the GFile down to the bottom and get its filename at the very
end where it's actually needed.
