Comment 1 for bug 392693

Could you test with a recent development build from <http://inkscape.modevia.com/macosx-snap/?C=M;O=D> if your problem still persists?

It might be helpful to know more about your system setup (version, any macports/fink installs, other) as both stable and dev builds seem to be running without your described problems on default OS X installs.
