Audio glitch on metadata update in ogg stream

Using icecast 2.3.2, xine v0.99.6

When metadata is updated manually via the admin interface for an ogg
stream, there is an audible glitch when listening via xine.

When listening to the stream via ogg123 player there is no audible
glitch but I get the following messages.

Done.

Is the audio glitch caused by icecast server or is the xine
implementation buggy because ogg123 can play the stream without any
audible glitch?
