Same thing here I have Dapper Drake on a partition and recently install Knot 2 on another partition. The two installations share the same /home directory (partition).
On the desktop and in Places I see duplicated entries : hdc1 - hdc1(2) - data - data(2) -- [edgy] gnome shows duplicated mounts https://launchpad.net/bugs/57701 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
