Much, much closer. The only thing that shows up in the list now as dependent on arts is 
avidemux. While it is the same issue, in the ebuild, it has:

         arts? ( >=kde-base/arts-1.1.1 )

in the DEPEND line which probably messes something up. Other than that, your patch works 
great! You really should submit that patch on Bugzilla.
