I'm not sure if my problem was exactly the same bug (Brasero was producing coasters without any errors, but I was burning ISOs, not data CDs), but the patched version in the PPA fixed the problem for me nonetheless.

This finalizing messages is showing for the rest of the burning process (~10min @8x 8,5GB). After that, it ejects the media without any error. But when I insert the media again, nothing happens, except, that the DVD-Drive disappears from the "computer:///" location in nautilus. This problem only exists when burning On-The-Fly. Burning ISO Images or automatic creation of ISO Images before burning works without problems. The burning speed doesn't matter to this problem. I test 8x, 4x and 2x. All the same problem. On-The-Fly burning using K3B works quite well @8x speed. One thing I also notice is, that Brasero uses 100% CPU on one core, while K3B uses just about 5-15%. I attached the last Brasero log. I don't know, why it just says, that it was only at 49% and then says it's finished. The burning took about 28 minutes. The media was unusable on all my three devices (Linux/Windows).
