Comment 5 for bug 38918

Confirming based on rael9's report, along with the fact that it happened to me again, after I had fixed the issue by whiping my configuration.

This time it happened to me after my gnome-session was automatically saved prior to an automatic low-power shutdown. I was able to fix it by killing all instances of nm-applet, saving my session, then logging in again. This still doesn't make sense, however, because I never see two instances of nm-applet running when I am prompted for the password twice. Needs to be debugged.
