Bug Description
Most UDF media (eg DVD) have directories with this permission:
root@vostro:~# ls -ald /media/cdrom0/
dr-xr-xr-x 2 4294967295 4294967295 352 2009-05-28 08:49 /media/cdrom0/
But other UDF media (eg DVD) have this permission, lacking the execute permission:
root@vostro:~# ls -ald /media/cdrom0/
dr--r--r-- 2 4294967295 4294967295 768 2006-01-01 10:00 /media/cdrom0/
In the second case, it appears that the media can only ever be read by user root, because the directories do not have execute permission, and this means that on desktop insertion of the media, they behave differently from media where the first case is inserted.
It also appears that the udf filesystem options provide no means of working around this issue, as only root can cd into a directory that has no execute permission.
