I also had the problem that qt downgrade was forced by
app-text/poppler-bindings (& fixed it the same way). The crazy thing I
found was that it would keep downgrading then upgrading then
downgrading every time I ran paludis --install world.

After looking at the src, I think it's the poppler-bindings ebuild
which is at fault:

	cairo? ( >=x11-libs/cairo-1.4 )
	gtk? (
	qt3? ( =x11-libs/qt-3* )
	qt4? ( || ( ( x11-libs/qt-core:4
			x11-libs/qt-test:4 )
		=x11-libs/qt-4.3*:4 ) )"

I'm no ebuild expert, but I believe the last line is a bit suspect?
Surely this should be >=x11-libs/qt-4.3*:4 ? Or is that there because
Qt 4.4 uses split packages whereas 4.3 doesn't and the line is to
catch older, non-split 4.3 Qt versions?

I've had a similar problem with ffmpeg (being repeatedly downgraded
then upgraded again) but I can't remember the exact circumstances or
which packages were causing the up/down-grade.
