Brasero crashes when making a video DVD

[Lorenzo]

I tried to link this bug to #612251, but I can't find it starting from apport-bug, so I need to report a new one...
Bug is the same, I can add the apport report and the complete message that appears in console:

** (brasero:22343): CRITICAL **: brasero_track_type_equal: assertion `type_B != NULL' failed
**ERROR: [brasero] Horizontal size is greater than permitted in specified Level
