Unfortunately this doesn't give too much info since you don't seem to
have all debug symbols enabled. Could you try to reproduce this with
latest bluez git. You don't need to install anything but just compile
(./boostrap-configure && make) and run (src/bluetoothd -nd) from the
source tree directly. Then, it'd also be nice if you could use git
bisect to determine the exact commit between 4.69 and 4.76 that
introduced this regression.
Thanks.

Johan
