Scrobbling failure

[Szewcson]

When I trying scrobbling I got such errors:

I'm using basic.py as a script.

On my machine, the same error occured when I had two instances of rescrobbled running, one of which was started together with my X session from my .xinitrc
and the second one from the terminal.

So, a possible solution is to kill all other rescrobbled instances (killall rescrobbled)
