On a first approach, if ghostscript can render the ps pdftops generates 
correctly but Illustrator can not, it'd say it's an Illustrator bug not a 
pdftops one.

bugs.freedesktop.org is what we use to track bugs, as said i'm not sure this 
is a bug, but you can open a bug there and attach the file.
