avahi-client properly closes the D-Bus connection before unrefing it,
it should be as robust as a C program can be. (see avahi_client_free()
in avahi-client/client.c:612)

If you are encountering this problem it is most likely some kind of
programming error elsewhere, maybe you call avahi_client_free() more
than once on the same object?

Valgrind might help you find this misuse.
