Hi Evelyn, I just found this (sorry I didn't find it sooner).
"Starting with XQuartz 2.3.2, X11 has some functionality to exchange the content of the clipboard with OS X. But it currently does not know how to deal with vector images so it just captures the screen, i.e. creates a bitmap copy, and then pastes that. You need to deactivate this functionality in X11 preferences > Pasteboard: uncheck "Update Pasteboard when CLIPBOARD changes". However, this will also prevent copying text from any X11 application to Mac OS X ones. It will not prevent copying text from OS X to X11.
This is from the Inkscape wiki here.
