Ok, the profile selectino issue seems to be a race condition. I've just been able to reproduce the problem on xenial with bluez and pulse from yakkety, and restarting pulse always seems to fix the problem, and then it seems to work afterwards, no idea why.
Time to look at bluetooth patches since pulse 9 to see which one may fix the problem, although from a quick glance, this won't be easy to work out.
