See my bug #377373 https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/377373
You are telling that the fix was released on 2008-08-12 but I can still reproduce it!

# modprobe udf
# mount -t udf /dev/sr0 /media/cdrom0/
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so
# mount /dev/sr0 /media/cdrom0 -t udf -o ro,user,noauto,exec,umask=0,session=0,lastblock=1
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

It seems that udf module is loaded.
# lsmod | grep udf
udf 92584 0

I used commercial audio CD for testing which was bought in the music store. The same CD I am able to mount and listen in Ubuntu 8.10 32b!
Please raise the importance from low.
