MOC makes clicking sound when playing the next mp3 file

Hi,
When I use MOC on a ssh connection, on a RHEL 6 system. MOC makes a clicking sound when playing "the next" mp3 file.

It does not do that when I play flac files.

Does someone know if this a known error, or better, how to fix this?

cheers,
Marco

Is this a duplicate of http://moc.daper.net/node/586 and 709
(which are fixed in SVN r2252) or does the problem still exist
in a subsequent MOC build?
