Yes (except for slotted packages). A "normal" upgrade emerge removes
the old version.

Nope (except sometimes for slotted packages).

Depclean is for clearing out stuff that was installed automagically as
a dependancy but now doesn't need to be installed at all because

  1. Whataver pulled it in as dependency got manually removed.

  2. A package's dependencies got changed.

That happens for slotted packages and for things like kernel sources.

On my systems, the only things that typically get removed by depclean
are old versions of gentoo-sources and the occasional old slot of
binutils (or whatever).

When was tracker-miners-3.4.0 last built? It RDEPENDS on [1]:

">=app-text/poppler-0.16.0:=[cairo]"

So if tracker-miners was built with poppler:0/123, and if I'm
understanding "man 5 ebuild" correctly, it will require a 0/123-slotted
version of poppler to be installed. Given that tracker-miners accepts
any later version, rebuilding it will hopefully be enough.
