network manager applet disappears after invalid wired radius key

I went to school and plugged in cable. Cables there needs radius authentication. My password i used for radius timed out, so it is invalid. It asked me for key, i entered the same againt (i need to connect first to get new key :) Instead of new asking of password, or reporting failure, nm-applet disappeared.

When i tried again from command line, i got this:
$ nm-applet
** (nm-applet:3666): DEBUG: foo_client_state_changed_cb
** Message: <info> New secrets for EDUROAM/802-1x requested; ask the user
