[Adam Hunt]

After a reboot and second attempt to erase the CD-RW the initial error
reoccurred: "1. Probably a buffer underrun occurred, 2. please choose a
lower burning speed, 3. Blanking error, 4. Sorry no error handling yet."

As reported above Brassero was able to erase the CD-RW without any
problems. Brassero can also be used to record a data CD, but is very
slow compared to K3B.
