Problems with CD insertion - sid

[Oliver Elphick <olly@lfix.co.uk>]

When a CD is inserted, it does not get mounted (data CD) or properly
notified (audio CD).

I found that rhythmbox never showed an audio CD as available to play -
it should come up under devices on the left-hand sidebar.

I then tried setting the system to run VLC instead, using System
Settings.  Still nothing happens when a CD is inserted. (But VLC can
play the CD if directed to.)

I found that a data CD is not mounted when it is inserted; I had to
mount it manually.

The Debian version is sid - up-to-date.

I don't know where the problem resides.  Which package should I be
looking at?
