I'm on Inkscape 0.46 on a PPC Mac.
I created a shape (it's just a part of it, but the relevant part):

As you can see, it's just a bit of a curve, filled with a solid colour.
If I save it as an .eps, I get this (it's an image from Mac OS X Leopard's Preview app, which first converts the .eps to .pdf):

If I save as a ps or .odg, I get the same thing. When I open it in OpenOffice 3 (the odg), I actually get a white moon-slice over the curve which I can remove!
Interestingly, if I save as .pdf from Inkscape, it looks as it should.
Unfortunately, I cannot edit the eps after I save it from Inkscape and I really need to send an .eps to someone.
I tried doing this on Inkscape 0.45 included with my Ubuntu Gutsy and it does the exact same thing. Is there anything I can do to make it save as .eps (or .ps or .odg for that matter) correctly?
Thanks,
Dam
