I've found the same thing before, its a bug in artsd. I get the same thing
on Slackware 8/current.
artswrapper drops permissions before getting to this
in arts-0.6.0/arts/soundserver/artswrapper.c (nonrelated bits removed)
/* drop root privileges if running setuid root
(due to realtime priority stuff) */
if (geteuid() != getuid())
{
setreuid(-1, getuid());
}
if(argc == 0)
return 1;
argv[0] = EXECUTE;
execv(EXECUTE,argv);
perror(EXECUTE);
return 1;
}
