This sounds like the same problem I'm seeing (correct me if I'm wrong).
1) When I print from SketchUp to PDFCreator, everything looks fine.
2) When I import into Inkscape (0.46-pre1) and save as SVG, everything looks fine.
3) When I save as PDF/EPS/PS from Inkscape, the arrows turn into squares.
There is apparently a way to do it in PDF (as shown in step one), but I can't find a way to get Inkscape to save it that way.
Files showing steps 1, 2 and 3 are in the attached zip file.
