Description Wim Taymans 2012-11-15 10:39:16 UTC 
g_socket_join_multicast_group() and also g_socket_leave_multicast_group() don't work because the structure passed to setsockopt() is not properly cleared.

in g_socket_multicast_group_operation(), mc_req is passed to setsockopt but only the address and interface are set, the other field (imr_address) is left
to random values and causes setsockopt to randomly fail with ENODEV (No such device).
