Any progress in investigating the issue?  I hit this a few weeks ago
immediately after upgrading network-manager even without activating a hotspot
as I keep a monitor interface around for aircrack-ng purposes.  Today, I hit
it again when activating a hotspot.  It does seem quite silly that
network-manager tries to manage a monitor interface it itself creates for the
hotspot, and doubly so that it fills the logs complaining about it.  You're
lucky that you keep a separate partition just for /var/log. :-)

Anyway, the workaround I use is this in
/etc/NetworkManager/NetworkManager.conf:

[keyfile]
unmanaged-devices=interface-name:wlan1mon0;interface-name:mon.wlan1

(wlan1mon0 is the monitor interface that I created, mon.wlan1 is the one
network-manager creates itself)
