I'm going to ask a friend that's a whole lot smarter than I am to give this a look so I want to make a few observations.
(a) I get this in Ubuntu running Unity, Ubuntu GNOME running either GNOME Shell or GNOME Classic, and the Flashback sessions whether installed in Ubuntu or Ubuntu GNOME. (b) I've had no problem with Brasero creating data discs or burning iso images so I think any problem with Brasero is not particularly related to this bug. (c) I just performed a fresh install of Ubuntu Trusty using the 20140701 i386 daily image, fully updated it, and inserted a blank DVD which did reproduce this bug, but you can see from the attached screenshot that 'gnome-settings-daemon' is NOT installed in a default Ubuntu installation so this is either NOT a 'gnome-settings-daemon' bug or it also effects 'unity-settings-daemon'. ** Attachment added: "Screenshot from 2014-07-03 00:07:34.png" https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1069964/+attachment/4144349/+files/Screenshot%20from%202014-07-03%2000%3A07%3A34.png -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1069964 Title: Unable to mount Blank CD-R disc.
