Just an FYI, I had this same problem. I did an upgrade from Dapper to Edgy as well.
I suspected that there was some incompatibility so I removed all themes from my ~/.themes and /usr/share/themes and then reinstalled the ones I cared about. This fixed the problem. -- gnome-theme-manager hangs, stops updating UI https://launchpad.net/bugs/68578 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
