With respect to the discussion on how to integrate wmf into scribus, I just discovered that there's a package called libwmf provided by almost all Linux distros. It contains executables as wmf2eps, wmf2fig, wmf2gd, _wmf2svg_, and wmf2x. It would mean yet another dependency, but it may be something worth thinking about, and it could save some time otherwise wasted in creating another import filter.
