I also encountered the problem via poppler, and fixed it by masking the
unneeded qt.

$ grep qt /etc/paludis/package_mask.conf

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:

RDEPEND="~app-text/poppler-${PV}
        cairo? ( >=x11-libs/cairo-1.4 )
        gtk? (
                >=x11-libs/gtk+-2.8
                >=gnome-base/libglade-2
        )
        qt3? ( =x11-libs/qt-3* )
        qt4? ( || ( ( x11-libs/qt-core:4
                        x11-libs/qt-gui: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?

Yes, that's the explanation: Qt 4.4 uses split packages, but poppler can still use the non-split Qt 4.3.

Best,
Ben
