Cannot umount through nautilus context-menu

[Nanley Chery]

Binary package hint: gmountiso

When I try to umount a gmount-iso-mounted-iso (what a mouthful) through the nautilus context menu, I receive the following error:
|Unable to unmount cdrom0 |
|umount: /media/cdrom0 mount disagrees with the fstab|
A user should be able to umount an iso through the context menu without having to reopen the application.

Is this symptom reproducible in 8.10 or 9.04?

[Nanley Chery (nanoman)]

I still have this error in 8.10 - screenshot attached. One option to make this work is to use policykit - much like the way we do now to mount/umount disks.

I've had this error in Hardy & Intrepid -- is there any chance it will be fixed by the creators of GMount-iso?

[Joe Davison (joesephus)]

Confirm - I have had this error.

Doing sudo umount /media/cdromX did the trick. (change X respectively)

Still an issue in Maverick
