This can happen if Sid has dependency issues.  For example, if you do a
'dist-upgrade' when only part of a large package (such as KDE) has been
properly migrated to Sid, you might find that apt will remove KDE
because it can't satisfy all its dependencies.

This will normally be fixed within a few days.  This is one of the
down-sides of using Sid.  If you don't want it to happen, only use
'apt-get upgrade' or watch carefully before doing a 'dist-upgrade'.

The above behaviour will not happen with Stable or Testing.
