Is what the case? kde3 and kde4 need to have different prefixes, but still you
have one of them first in your $PATH, so when you launch a kde3 application it has
to find the kde3 helpers and not the kde4 helpers (which is why I renamed kbuildsycoca,
and earlier on started to move some more internal helpers to lib/kde4/libexec).

Or did you mean about XDG_DATA_DIRS? It needs to be unset, if you set it to "/opt/kde4 only" before,
so that /usr/share/mime is found.
