Comment 7 for bug 846441

Ahhhh... Ok. Now I can figure the problem and I already fixed it for few days, also if I didn't experience this exactly issue I also considered this aspect when killing the unity-panel-service: I'm sure that if in a terminal you run "killall -9 unity-panel-service" (in a single screen too), you get the very same problem.

The fact is that unity-2d trunk currently doesn't manage an indicator removal, but I implemented that since Sept 9th in my branch lp:~3v1n0/unity-2d/unity-core-indicators-revisited so I guess that you just need to merge this proposal to fix the issue: https://code.launchpad.net/~3v1n0/unity-2d/unity-core-indicators-revisited/+merge/74715

@Colin, if you can, please compile that branch and let me know if you still get the issue with that. Thank you.
