I've got a problem with my bluetooth drivers on my Ubuntu 16.04 machine. When I first load the OS, I can see the bluetooth tray icon, and even connect to my bluetooth headset. The moment I try to stream something to the headset, the bluetooth crashes, and I can't reactivate it in any way other than restarting my computer.

This has already happened with 2 different headsets, so I doubt it has anything to do with these headsets.
After the bluetooth crashes, this is what the bluetooth manager looks like:
As you can see, even though I activated the bluetooth, it is disabled. And even though the "Show bluetooth status in the menu bar" is checked, I see nothing.
I tried to reinstall bluez, with no change.
Thanks for the help!
