No option to wite to DVD-RW or CD-R

[jeremy-list]

To replicate:
Method one: in Nautilus: right-click an iso file and select "Open with Disk Image Writer"
Method two: in the Disk utility: select the blank disk and find "Restore disk image" in the menu

Expected results:
If there is a blank disk in the drive: either method should be able to write an image to the disk.

Actual results:
Following method one: the blank disk will appear greyed out in the list of write destinations. Following method two: the "Restore disk image" option will be greyed out.

Confirmed with multiple blank disks: both CD-R and DVD-RW. Issue is not hardware, drivers, or blank media: K3B is able to burn disks correctly.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.
