[Bug 646902] Re: Brasero crashes when trying to burn without an active GNOME session

[Mario Limonciello]

** Description changed:

+ Impact:
+ Brasero is only usable in desktop sessions that include GNOME.  Running in KDE, Openbox, XFCE, or any other environment causes a crash.
+ 
+ Addressing:
+ The bug has been fixed upstream and is in the next release of Brasero already in the current development Ubuntu release (natty).
+ 
+ Minimal Patch:
+ http://git.gnome.org/browse/brasero/patch/?id=3775cd7fc7d15aa03131a1d5cdccf57f185e2b92
+ 
+ TEST CASE:
+ 1) Install Kubuntu
+ 2) Install Brasero
+ 3) Attempt to burn a DVD
+ 4) Observe a crash
+ 
+ Regression Potential:
+ Regression potential is low, the patch that's included is just properly cleaning up after an error when the system was unable to inhibit suspend due to GNOME not running.
