If you rebuild anyway, why not using the latest stable version 2.4? This is already solved since quite some time. A recompilation can't be a solution TBH, as the bug is in that version, recompiling doesn't change anything in the source.

I also strongly suggest you get a newer KDE, current stable is 4.6 and there have been many bugfixes since version 4.4.5. Amarok depends on Qt 4.6 which is available only since KDE 4.5.x

Comment 2 Lyall 2011-02-27 12:32:20 UTC

Thanks for the prompt reply.
I am not using 4.5.x because, under Gentoo, that is not marked 'stable' in Gentoo portage.
I will push for Gentoo to mark KDE 4.5 as stable (as opposed to ~x86 in gentoo speak).
BTW. Rebuilding does fix the problem, for me. I generally assume it's because I have had some underlying kde libraries re-built but maybe it's some config file which is reset on re-build.
