I just ran into the same problem when uninstalling virtuoso. After sudo apt-get install virtuoso-vad-rdfmappers the message about the virtuso RDF plugin missing disappeared.
Hence virtuoso-vad-rdfmappers seems to contain the missing dependencies. This message marked as wontfix seems to be a duplicate: #671391, As the problem is recurring it should be fixed. In 671391 the following reason is given for not fixing: "kde-runtime has already a recommend on virtuoso, and it's more than enough given that a) any KDE application depend on kde-runtime b) the semantic desktop is an *optional* feature So no, an hard dependency will *not* be added." If the semantic desktop is optional and depends on virtuoso, uninstalling virtuoso should disable the semantic desktop in a consistent way. Uninstalling libnepomuk4 will remove 150+ packages like kwrite and ark. So if the semantic desktop is optional and depends on virtuosol libnepomuk4 may not be the right place to put the dependency. A package "semantic desktop" with the appropriate post-remove script might be more helpful. Why does Nepomuk show a warning at all if an optional feature is not installed?
