You may be able to use something along the following lines:

$ aptitude search '?narrow(~i~n(kde|qt|plasma),!~V4:14.0.5-0)'

"From all the available versions of all packages, narrow the selection
down to installed ones (the ~i term) with names containing kde or qt or
plasma (the ~nregex term), and from those filter those whose version
does not match the current Trinity release version."

The results marked with A in the second column were automatically
installed so focus on any that don't have this marker.  "aptitude why
<package>" may help here.

Hope this helps, aptitude search terms can be tricky but are also pretty
powerful.
