Description:

Reporting a new bug in the dapper preview:

When the CD-ROM tray is open, or when it is closed with a CD inside
which has been manually unmounted, you can "mount" the CD-ROM drive from
the Places, Computer  location in Nautilus. (Right click, Mount).

This does not work properly in dapper. You can click that menu item, and
an empty error box will appear (no message in it). In .xsession-errors,
the message

closing

is output.

This worked fine in breezy I think. In any case, it has been working in
the past.

Other actions in that menu appear to work. Ejecting after mounting works
fine. Closing the tray works fine. Just mounting does not.

Issueing a "mount /cdrom" or "pmount /cdrom" from a terminal works fine
too, closing the tray and mounting the disc.

I hope the description is clear enough to reproduce it. Thank you :-)
