If one installs this one, the following would be removed:

Remv libqt3-mt-dev (3:3.2.3-2 Debian:testing)
Remv x-window-system (4.3.0-5 Debian:unstable)
Remv x-window-system-core (4.3.0-5 Debian:unstable)
Remv xlibmesa-dri (4.3.0-5 Debian:unstable)
Remv xlibmesa-glu-dev (4.3.0-5 Debian:unstable)
Remv xlibmesa-gl-dev (4.3.0-5 Debian:unstable)

Since I was running without x-window-system until now, I suppose I could let 
that go but the other stuff?

I rarely succede in actually using libqt3-me-dev but presumable should be able 
to use it. What about the rest of xlibmesa? All the stuff in brackets?

What gives here?
