This bug report was fixed with Brasero 2.30.2 for the original reporter. The other bug is still open, marking it a duplicate will mean it is also fixed. I would suggest filing a new bug by opening a terminal and typing
ubuntu-bug brasero
for Ubuntu 10.10. also, please make sure other applications are working. Will exaile or kb3 burn the disc and eject it? If not, it may not be brasero that is causing issues for you.
