dvd drive eject button failed to close tray properly

When I try to close the tray with the Samsung SH-D163B dvd drive eject button, it closes. But then opens again. This bug occurs in Ubuntu 11.10 and (X)Ubuntu 12.04 LTS. I can only close the tray properly with command eject -t /dev/sr0 and by closing the tray manually. (The Samsung SH-D163B dvd drive eject button works properly in Ubuntu 10.04 LTS.)
