Binary package hint: udev
I am seeing the identical behaviour as reported under Bug #283316. I'm running 10.04 with all updates applied as of 2010-05-16. /dev/sr0 ejects using right-click->eject on the desktop, "eject sr0" from the command line, and by pushing the eject button on the drive. Under all three methods, the drive bay opens then immediately closes. My second optical drive does not exhibit the same behaviour.

It seems to be fixed for almost all other people, this seems to be the only remaining report.
If you can still reproduce this, please do
udevadm monitor -e --udev
then open the CD-ROM drive (by any method), let it automatically close again. Then press Control-C and copy&paste the output (you might need to scroll up). Thanks!
