I think that the rogue line is added to the interfaces file if you use the Manual Configuration option that Network Manager presents (more specifically the window that opens when you hit "Configure Interface" in the Manual Configuration application, and which lets you directly specify an ESSID to connect to). If you remove said ESSID from said window it doesn't remove the line. The presence of this line then causes NM to (deliberately?) fail to present a list of wireless networks in the system tray menu. This seems like odd behaviour - the NM manual configuration app is effectively disabling a major feature of NM!
