libre.fm scrobbler doesn't work

When I set listen to scrobble to libre.fm nothing seems to happen. The libre.fm site says I haven't scrobbled anything yet. With last.fm scrobbling works fine. When listen tried to submit to libre.fm I get the following output on the console:

Sending handshake to Audioscrobbler.
Handshake SUCCESS 0fe18c26d1372bd3853e325e9ad96da3
Sending song: Parov Stelar - Crushed Island - 1278339465
