I have a very similar problem with Kubuntu Edgy (upgraded from Dapper months ago): no desktop icons, can't mount as user, and when I click on the stick in media:/, it just looks empty. No error message about failure to mount.
No error message on trying to Safely Remove a USB stick that was mounted by root, either. -- Not possible to mount USB stick after upgrading to kde-3.5.5 https://launchpad.net/bugs/65662 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
