grip/lenny doesn't extract audio CDs first tracks

[Nicolas BERCHER <nicolas.bercher@teledetection.fr>]

Hi,

On one of my Debian systems, grip is unable to extract the first track 
of any audio CD.
$ apt-cache policy grip
grip:
 Installé : 3.3.1-15+b2
 Candidat : 3.3.1-15+b2
Table de version :
*** 3.3.1-15+b2 0
       500 http://ftp.fr.debian.org stable/main Packages
       100 /var/lib/dpkg/status

On another computer with the same grip version, it works good.
Could that be related to a CD drive problem? Any idea?

Nicolas.
