No, I haven't tested the git master. The GUI freeze isn't a deal breaker for me
as I normally do use smaller playlists and it doesn't affect audio when it
freezes. I reported as I thought it might be worth looking into.

The collection is local.

Which Phonon backend?
Where are those tracks located (local, remote)?
Since you use Gentoo: did you try the current git master instead? it is about
500 commits ahead of Amarok 2.8.0, and I see no freezes on track change at all,
might well be something already solved.

I start with an emply playlist due to the fact you just mentioned. The startup
is very slow. Around 20 seconds. 

My report is about the freezing of the GUI 4 seconds after you change tracks
when you have a big list loaded and not about the startup.

And to be more precise: this is not "fixable" in the current architecture, it
would need a complete rewrite.

no, not all players handle playlists the same way as amarok does, the more
tracks you put in the playlist, the more tracks have to be checked for
availability on startup, and that can substantially slow down the startup
procedure.
Just don't put all your collection in the playlist, use the playlist generator,
smart playlists or the collection filters instead.

Sad to hear that this is the attitude when it's clearly a bug. If it were a
"side effect" as you so put it all players would have it. 

If there's been many reports about it baffles me even more why there's no
desire to fix it.

no wonder, you are not meant to put your entire collection in the playlist,
there have been many reports about this, this is not a bug but a normal side
effect. Sorry if this is not how you intend to use it, but this is definitely a
use case we do not cater for.
Use the various playlist capacities of Amarok instead.
