Volume Normalizer plugin for XMMS

see http://bugs.xmms.org/show_bug.cgi?id=1409

Clicking on a shoutcast .pls url in a browser does not
work the *second* time you do it. For example,
clicking http://somafm.com/groovesalad.pls will launch
xmms and begin playing the shoutcast stream
successfully. But subsequently clicking
http://somafm.com/beatblender.pls will cause xmms 1.2.8
to hang.

Observed on Redhat 9.0 with emu10k1 OSS audio, galeon
1.2.7, and xmms 1.2.8 compiled from source.

I have determined that this behavior occurs when I
enable the volume normalizer plugin. I experience this
bug when volnorm-0.4.1 or volnorm-0.8.1 is enabled with
xmms 1.2.7.
