Public bug report changed: https://launchpad.net/malone/bugs/30081 Comment: Current versions on my system are: nautilus: 2.13.4-0ubuntu1 libgnomeui-0: 2.13.3-0ubuntu1 libgnomeui-common: 2.13.3-0ubuntu1 (I've been upgrading daily since Flight 2, no idea when thumbnailing disappeared, as old thumbnails still exist)
