after i rebooted with another OS (knoppix), this time the emergency gnome worked, i opened the gnome-theme-manager and i got the same error as before, here it's the automatic report, i'm sorry i can't say much more, how noob i am :(
hovewer i'll guess now i should purge the themes that doesn't belong to the standard ubuntu and desist exploiting the gnome-look's goods, it's better if i don't mess with themes or similar things ** Attachment added: "bug notify's created bug report" http://librarian.launchpad.net/5786561/_usr_bin_gnome-theme-manager.1000.crash -- gnome theme manager crashed (but not during the gnome standard session) https://launchpad.net/bugs/79583 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
