Ok - I've had 5 seg faults in the last 24 hours which is a pain, as
you can imagine.  I crona  script once per minute to restart Icecast
in the event that it fails so the service is never down for more than
59 secs but it drops encoder/client connections in that time.

However I now have some clues - preceding each seg fault I get this:

or here's another:

Currently looking at status.xsl at my rogue webcaster there entry for
this chap is thus (names changed to protect the innocent/guilty):

Stream Title:	Radio FM
Stream Description:	Radio FM
Bitrate:	32
Stream Listeners:	0
Stream Genre:	Various
Stream URL:	http://path.to.my.server:8000/radiofm.mp3
Current Song:	r›uX��s�7_�n?�GYF��冄<+R���V%��(:�)��oE��pX��!k�)~�w�+c5�2O�1f��GhE�2*��xC�6�LzFH��"��/*���H5��皠�G��,�L�7M�f̥Z��
Listen:	Click to Listen

The stream plays fine but the song title is obviously borked.

I have only recently switched to this new server setup (FC8,
2.6.23.9-85.fc8) and my previous instance of Icecast was not
vulnerable to this problem - could this be something like I don't have
Unicode/UTF8 installed?

As my previous Icecast installation was not vulnerable to this issue,
I think there must be something that can be done server side to
accommodate this webcaster who is sending us this 'broken' metadata.

Many thanks in advance for your help.
