Error was partly found via my error. Icecast2 was running from a prior session
on 8020. Unknowning to that I tryed to start it again w/ my only config which
uses port 8020
# ./icecast -c ../icecast.xml
Could not create listener socket on port 8020
Changed groupid to 99.
Changed userid to 99.
Segmentation fault

Granted this isn't a major issue but couldn't it just terminate peacefully if
the listener socket is unavail
