That's a good question. The thing is that "why" doesn't tell you what
"install" did; it just traces out dependencies blindly. It's picking
the alternative because it's "shorter" than the path through a provides.

You mean that you did this, right?
(a) mark imagemagick for installation
(b) disable djvulibre-desktop
In (b), aptitude will only automatically clear installations of
packages that nothing requires. If hal is being autoinstalled, it
doesn't know the difference (any more) between hal being autoinstalled
for djvulibre-desktop, or for one of the approximately 5,000 other
packages that think they need it.

At the moment, aptitude doesn't attempt to figure this out.
