@Emily: Was that a version of LibreOffice 4.0.x on both Ubuntu and OS X? And what release of Ubuntu are you using?
LibreOffice on OSX seems to be using fontconfig-2.8.0. Both Ubuntu Quantal and Raring use newer versions. So a solution might be updating fontconfig on OSX (and possibly: upstream any Ubuntu-vendor patching first).
lowering priority as for upstream, this doesnt fit in 'critical' (not a crasher or dataloss involved).
