I just had this happen to me. From Nautilus (Ubuntu 12.10), right clicked on an iso file-> open with Brasero. Blank CD in drive. Dialog Estimating File size dialog displays, but never progresses.
Turns out some utility (Nautilus? Some add on?) had taken ahold of the blank disk allowing you to drag and drop files to the blank disc for later burning. As soon as i unmounted the blank disk, Brasero took off and burned my image on the first try.
I'm sure there is some system setting that tells Ubuntu how to handle blank disk insertion.. I never changed that from its default setting.

Hope this helps!
