Hard to say for sure. It looks like there is a binding to the width of something. If you don't have lots of binding expressions maybe you can find the binding to width (probably from DashboardIcon.width)
Also, further down in the stack trace, I see: "Cannot create property icon on components.DashboardIcon." That makes me wonder if you have a different DashboardIcon in the source paths of your Mac build. I think if you SWFDump the SWF it will show you the path to the actual DashboardIcon that was used.
