[Bug 1710941] [NEW] Bluetooth stopped working after update

[Doug Morse]

Public bug reported:

Bluetooth connection to Bose Soundlink II have been fine for years.
Applied a few new updates in the last day or two --- system was
generally up to date, I don't often wait more than a week or so --- and
now I can no longer connect.  Removed the device and re-paired just
fine, although the speaker did not connect as it usually does after the
pairing (i.e., it stayed in pairing mode).
