Okay, I just found out where this is coming from and how to fix it. Grepping /var/log/kern.log for part of the connection name (not UID) gave me the answer:

Once you actually go to bluetooth manager and remove the connection from there, it is then listed in nm-applet as "Unmanaged" until the next reboot where it's gone and stays gone. Still an usability bug IMO. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1638946 Title: Mobile broadband / Bluetooth connections cannot be permanently removed from Network-Manager Status in network-manager package in Ubuntu: Confirmed Bug description: In network manager, there are a few obsolete cellphones listed whose bluetooth connections I once used to go online. I can't remove them permanently. They don't show up in/etc/NetworkManager/system- connections/, I can't find them in gconf-editor either. I can remove them until the next reboot using either the "Edit connections..." dialog in the applet, or by issuing 'nmcli connection delete uuid XXXXX' at the command line, but they always show up again after the next reboot.
