Ok, I think I have found out the steps to reproduce this
It isn't as often as I initally reported
The way I am reproducing is below
1. start playing music using the appindicator
2. ensure banshee is not open
3. using empathy type a message to someone
4. using the appindicator open banshee
5. banshee should open full screen
6. the menu on my pc still says Empathy Internet Messaging
Have attached screen shot hopefully to better explain the last 2 steps
