This is caused by a pa_core_assert_ref inside an unlink function.... It seems this is not valid when shutting down the server as pa_core_unref() unrefs itself (thus ref-cnt==0), calls pa_module_unload_all() which in turn triggers unlink hooks. So two solutions: 1. Remove such asserts from those hooks that need it. 2. Re-ref/unref the core inside it's free function. 3. Call pa_module_unload_all() && pa_scache_free_all() before calling pa_core_unref(). 2 is hard to do (can't ref something with a ref-cnt already at 0) and 1 is a bit ugly as it imposes different rules on you (i.e. if the core state is shutdown, then don't use the core), so I think 3 is the right approach.
