Brasero crashes just after blank disk recognized

after choosing Disc Copy and copy to same drive the disc was read and ejected. After inserting a blank disk Brasero exitted. The log file in /tmp seems to indicate it received a HUP signal. Burning the image left behind in /tmp seems to work OK.

I am using Brasero V2.32.1 on Ubuntu 11.04 (Natty Narwhal)
