I can confirm this behaviour here. I am running only nm-applet (on top of course of the system-wide NetworkManager daemon). Sometimes, out of the blue, some networks won't work. For example here, i have an internal *and* external wifi card. NM can connect to network "foo" fine with the internal card, but the external card yields this error:

I tried removing items from the config, they are recreated when using the internal card (which is also odd). This bug looks like those as well: https://bbs.archlinux.org/viewtopic.php?id=203374 http://forum.xfce.org/viewtopic.php?id=7458 http://ubuntuforums.org/showthread.php?t=1973863 so it is probably not debian specific, but seems common with non-Gnome setup (e.g. XFCE above). Oddly enough here, restarting `nm-applet` fixes the problem. It prompts me for my gnome-keyring passphrase (which i never setup, i believe), i dismiss that dialog and then things work fine. really odd. A.
