Thanks for this report, it's very valuable.

Yes, I agree with your position. Starting to port now and then not having an
Amarok release for a full year wouldn't be good. We would lose direction and
our users (who are used to our rapid release cycle) would become impatient.
If we are to make a 1.5 release, we could also start to remove all X11
dependencies, in order to make the final move to KDE4 easier.

This does not change my position regarding our icon theme. I maintain my view
that it must stay default, otherwise it's next to useless.
Distributors can patch Amarok very easily to change this behavior, if need be.
So I think they are complaining over a non-issue.

Well yes, remember that I had raised exactly this issue back at K3M? But
apparently only SUSE is concerned about this issue, and at K3M the tenor was
to just not care about it. I guess this needs further discussion.

I agree stability is absolutely crucial. But I have yet to see evidence for
instabilities with our latest releases. We monitor user feedback constantly,
through bug reports, IRC, and forums, and I have not seen any alarming
reports lately. What gives?
(And yes, I realize you've probably been talking to Dirk ;)

Interesting. But is Kexi well maintained, and is it relatively guaranteed that
this stays so? What if Kexi development comes to a halt after we have
switched? I'm cautious about introducing any new KDE dependencies.
