Music playback does not re-start in Bluetooth speaker following incoming phone call

[Richard Huddie]

krillin ubuntu-rtm/14.09-proposed build 4.
bluez 4.101-0ubuntu19 armhf

SUMMARY:
When a Bluetooth speaker is connected to the krillin and playing music, after an incoming call is received, it is not possible to resume playback on the Bluetooth speaker without restarting the music app.

STEPS:
1) Pair and connect the Bluetooth speaker (BQ Altavoz Bluetooth Strauss)
2) Start music playback
3) During music playback receive an incoming call
4) Reject the call from the krillin
5) Try to resume music playback

EXPECTED RESULT:
The music should continue to play back through the Bluetooth speaker from the point when the call was received.

ACTUAL RESULT:
The music app indicates it is playing the track, but there is no music heard. It is not possible to play the music through the Bluetooth speaker without re-starting the music app. When the music app is re-started, music will play through the Bluetooth speaker again.
