 Nice oversight.

 We can't do anything about it for 3.5 because of binary compatibility, so 
there the only fix can be altering the calls so that they're not ambiguous.

 IMHO for KDE4 the solution should be moving KPassivePopup from kdeui to 
knotify as I don't see why any app should need to use it directly.
