I tried different things but it still crashes the same way:
- Compiled with GCC 2.8.1
- Compiled with GCC 3.2
- Commented out line 129 in vorbis-tools-1.0/share/iconvert.c 
  as of BugID 243 and recompiled/reinstalled
  [The tries above I actually did it with this version]

Compile log looks good. As there seems to be some problems with iconv 
(as of BugID 243) I show you this:

REMARKS:
- ogg123 just works fine (file wich I partially could generate, and 
  downloaded files)
- Version 1.0 missing in Bugzilla form
- sox works as I use it with lame


Let me know if you need more information.

Thanks,
