Just to add to this, it appears that this only occurs if you do not have a password initially set for gnome-keyring.
I ran /usr/lib/gnome-keyring/gnome-keyring-ask -d from a terminal. Set my password and attempted to connect to a network using nm-applet. No problems this time. -- gnome / nm-applet / keyring crash. https://launchpad.net/bugs/44753 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
