I think I should make clear what I mean by "no profile is selected" as I just realized a problem with that statement while on #bluez.
There are bluetooth profiles and audio profiles. Bluez must determine the bluetooth profile (is it a headset, a remote control, etc) and Pulseaudio must determine the audio profile (HD Stereo, Telephony full-duplex, etc).
I don't think any bluetooth profile is chosen by bluez, so pulseaudio doesn't know there's any device to chose an audo profile for. Once the bluetooth profile is chosen manually, in blueman, pulseaudio immediately connects and redirects audio.
