This bug is very similar to bug #329146: https://bugs.launchpad.net/ubuntu/+source/brasero/+bug/329146
If you are using vmware and a connected iso file you are probably seeing the other bug instead (try disconnecting iso and see if that solves it). Also, if the symptoms appear with nautilus show_desktop gconf value set to true (i.e. default setting).
