The bug is only partly solved with Gusty. In Feisty it persists completely.
I now report 2 different experiments:
1. using a commercial 9GB-DVD-ROM here which definitely contains UDF-extensions
Gusty correctly automounts with udf.
Feisty automounts with iso9660, here output from
'cat /proc/mounts' -> /dev/scd0 /media/cdrom0 iso9660
ro,nosuid,nodev,noexec 0 0
executing your proposed command 'mount /media/cdrom0' mounts iso9660:
'cat /proc/mounts' -> /dev/scd0 /media/cdrom0 iso9660
ro,nosuid,nodev,noexec 0 0
Manually I can mount the DVD-ROM as udf:
[EMAIL PROTECTED]:/home/ingo# mount -t udf /dev/sr0 /media/cdrom0
mount: block device /dev/sr0 is write-protected, mounting read-only
'cat /proc/mounts' -> /dev/sr0 /media/cdrom0 udf ro 0 0
2. I have got a DVD-R here, which contains files > 2GB, so it must use udf:
This DVD-R does not automount at all, neither under Feisty, nor under Gusty
It spins up twice after inserting, keeps spinning for a while, then stops
without beeing mounted.
No Icon showing up on the Desktop, device not listed in /proc/mounts
executing your proposed command 'mount /media/cdrom0' mounts iso9660
without icon on desktop:
mount: block device /dev/scd0 is write-protected, mounting read-only
'cat /proc/mounts' -> /dev/scd0 /media/cdrom0 iso9660
ro,nosuid,nodev,noexec 0 0
which definitely is wrong!
Manually mounting using the '-t' option works fine:
mount -t udf /dev/sr0 /media/cdrom0
mount: block device /dev/sr0 is write-protected, mounting read-only
'cat /proc/mounts' -> /dev/sr0 /media/cdrom0 udf ro 0 0
and DVD-ROM is completely readable.
So, conclusion:
partly solved in Gusty (probably as long as filesize stays below 2GB), but
still present in Feisty.
With filesize > 2GB (up to 4GB should be ok for UDF anyway), bug persists in
Gusty and Feisty.

Mounting UDF should be preferred over ISO9660
