The segfault appears to actually be in arts.  It's got a bad pointer. 
 
It looks like ogg123 (in another thread) was handing data to artsd: 
#0  0x1568f686 in sigsuspend () from /lib/libc.so.6 
#1  0x1561f36a in __pthread_wait_for_restart_signal () 
   from /lib/libpthread.so.0 
#2  0x1561bc6b in pthread_cond_wait@GLIBC_2.0 () from /lib/libpthread.so.0 
#3  0x0804a772 in submit_data_chunk () 
#4  0x0804e16d in play () 
#5  0x0804dd5c in main () 
#6  0x1567ca07 in __libc_start_main () from /lib/libc.so.6 
 
And artsd crashed while trying to start up, on this thread: 
#0  0x15fd725c in Arts::StartupManager::startup() () from /usr/lib/libmcop.so.1 
#1  0x15cf2930 in Arts::The_WaveDataHandle_impl_Factory ()
