I'll be happy to add the info you request to the bug report if it will
help, but I don't think it will.

The gnome-volume-manager automounts media-volumes for users *without*
having a mountpoint exist or having any mountpoint info, etc,. in
/etc/fstab. The debian version uses hal, udev and pmount to do this.
gnome-volume-manager has pmount with fixed options hardcoded into it:

josh@spleen:~$  strings /usr/bin/gnome-volume-manager | grep pmount
/usr/bin/pmount-hal %h
josh@spleen:~$


The problem is that dvdrw's get auto-pmounted by gnome-volume-manager in
rw mode, which makes the volume unreadable, since blocks get changed
when mount rw. unmounting the volume by hand in a terminal window
reports a dirty dvd+rw. the same volume is readable if mounted by hand
with the read-only flag.

Either gnome-volume-manager needs to be able to pass a read-only mount
flag to pmount when it automounts a dvdrw, or pmount/hal needs to detect
an rw and automagically mount readonly.

I didn't change anything in fstab and there is no entry for cdroms or
similar in it (well, actually, I did change it...I removed all those
entries that I had added years ago to user mount cdroms, since
gnome-volume-manager mounts them for the user...), so this wouldn't tell
you anything.
