Can't eject disk after burn

[Kyle Hopkins]

Release: Ubuntu 12.04 LTS on MBP 8,1

Package: Brasero 3.4.1-0ubuntu1

Expected outcome:
After brasero is finished burning the disk, it should be automatically ejected.

What happens instead:
Brasero tells me that it can't eject the disk and to eject it manually. However, the disk will not eject until after the computer is restarted.

Steps to reproduce:
Burn a disc using brasero.
When the dialog comes up saying the eject failed, press okay, then try to eject the disk manually.
