When portage suggests a USE change due to a blocker, the "culprits" are
listed from "smallest" to "largest". So in this case,
kde-plasma/plasma-pa is the culprit: a quick `less $(equery w
plasma-pa)` shows that plasma-pa is depending on gconf and
pulseaudio[gnome].

If upstream has decided to depend on gconf, it makes perfect sense to
depend on PA with the 'gnome' USE flag. This is probably so plasma can
correctly run as a user and keep track of file/sound settings.

The KDE team can likely explain *why* this change happened, though you
might want to check the homepage for plasma-pa first. The KDE team can
be reached via the mail alias (kde@g.o) or on Freenode via #gentoo-kde.

I hope this helps clear things up for you.
