Comment 12 for bug 72609

"I have encountered this same issue using k3b in Hardy Heron x86_64. After the write is complete, k3b commands the drive to eject the tray. I'm only guessing it sends another command to load the tray so it can begin verification. Unfortunately the tray fails to close. Loading the tray manually has no effect. k3b at this time is frozen, driving the CPU% between 50% and 100%, and will not respond to any mouse clicks. I then have to kill k3b from within System Monitor."

I have the exact same problem using x86_64 Kubuntu Hardy.
