Something very similar happens if you input the user password, but leave the group password blank.
In my case, I entered my user password, and accidentally hit enter instead of tab, and the NM Applet disappears just like above. I think that the above might be crashing for a similar reason as he doesn't input a username field, only the group password. -- nm-applet dissapears after connecting to vpn https://launchpad.net/bugs/92570 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
