Public bug reported:

What happens?
1. connct a2dp device
2. start playback
3. reconnect a2dp device from remote
4. ubuntu reports device is connected
5. a2dp device does not show up in pulseaudio nor does music playback work (via a2dp device). sometimes there are "timeout" error messages in kde.
6. try to reconnect from ubuntu, restart bluetooth daemon, restart pulseaudio daemon. it all does not help.
7. what does help is restarting 1. dbus 2. bluetooth and 3. pulseaudio then connect the device (if not already auto-connected)

After step 3, there is the following error message in syslog (no other
errors in syslog or dmesg):

pulseaudio[7812]: [bluetooth] bluetooth-util.c: Failed to release
transport /org/bluez/7791/hci0/dev_C8_84_47_10_24_A2/fd2: Method
"Release" with signature "s" on interface "org.bluez.MediaTransport"
doesn't exist

What I expected to happen?
After the device reconnect, the music playback switches playback back to the bluetooth device.
