Almost every time I try to tether to my Moto X running Cyanogenmod 12.1 nightly, it fails. (It worked once.) The failure looks like: Jun 10 18:19:47 antithesis gnome-control-center.desktop[7143]: Agent unregistration failed: GDBus.Error:org.bluez.Error.DoesNotExist: Does Not Exist 'g-io-error-quark' Jun 10 18:19:51 antithesis NetworkManager[1016]: <info> ([redacted]): Activation: starting connection 'Moto X Network' Jun 10 18:19:51 antithesis NetworkManager[1016]: <info> ([redacted]): Activation: Stage 1 of 5 (Device Prepare) scheduled...

I think this is a BlueZ 5.30 regression, so I'm reassigning this. FWIW, there are some other error messages in the logs I posted that might indicate NetworkManager or udev bugs.
Whoops, I forgot to include the link. https://bbs.archlinux.org/viewtopic.php?id=195681
Thanks for the report. Should be fixed in Rawhide now.
Are you planning an update for F22?
This still happens on Fedora 23.
This should be fixed in the future 1.0.x updates to F22 and F23. *** This bug has been marked as a duplicate of bug 1255284 ***
