Looks like a missing library.
OS X 10.10.3, xpra v0.14.24

That's an import loop: the client import gtk_util, which does gui_init(), which imports the platform stuf... and on osx, that involves loading the custom osx_menu class, which imports gtk_util again. At that point it is only partially loaded, and is missing scaled_image.
r9468 fixes that. I have uploaded a 0.14.25 beta build with this fix here: http://xpra.org/beta (note: there are many other 0.15.x builds in there too, those were not affected because gtk_util no longer does the gui_init)
If that also works for you, please close the ticket.
This fix does the trick, thanks!
