Nautilus fails to mount UDF DVDs properly

When I insert an UDF formated DVD Nautilus should automount it, and open a window presenting the files contained on the DVD disk.

Instead of this, the CD/DVD ROM icon disappears from the Computer location, and there is no window presented with the DVD files. It is as if the disk is not mounted at all. But this is not entirely true.

dmesg gives the following output:

[ 47.092792] UDF-fs: Partition marked readonly; forcing readonly mount
[ 47.118394] UDF-fs INFO UDF: Mounting volume '071129_0941', timestamp 2007/11/29 09:42 (1078)

So after all, the DVD was mounted!

cat /etc/mtab gives this:

/dev/sda6 / ext4 rw,errors=remount-ro,commit=0 0 0

Going to /media/071129_0941 manually shows 2 files, I presume they present the names of the 2 folders contained on the root of the DVD filesystem (I can verify this at the moment). Checking one of the files property (right click-> Properties), all I get is the files name, the Type is unknown and also the Size is unknown too.

I'm not sure if this is Nautilus fault or something else. Also I would mention that there is no fstab entry for my dvd rom:

# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sda6 during installation

Mounting ISO9660 formated DVDs is functioning normally!!!
