I have same bug.
This is backtrace from gdb

Problem triggers when
*update_track* calls *xmmsv_is_error* with NULL as argument
This function uses *xmmsv_is_type* that can't normally work with NULL
values (and prints this warning):
* xmmsv_is_type was called NULL value
* This is probably an error in the application using libxmmsclient
so, to fix this bug need to replace
---- lxmusic.c
1224 if( xmmsv_is_error ( value ) ) {
1225 return FALSE;
1226 }
----
to
---- lxmusic.c
1224 if( value == NULL || xmmsv_is_error ( value ) ) {
1225 return FALSE;
1226 }
