Whenever ending a skype call, rhythmbox start playing

[stone head]

Whenever i call someone on skype and he declines, or when a skype call ends, rhythmbox starts playing if open.

At first i didnt understand why this is happening, and then i realised that skype automatically stops rhythmbox when a call enters, and then plays rhythmbox when the call ends.

But what if i wasnt listening to music in the first place, and rhythmbox just happend to be open?

certainly not a showstopper, but an annoying behaviour nevertheless.
