To reproduce this, open totem, open a network location, let it play a bit, then
open another network location.

The problem is because when gst_queue2_open_temp_location_file() is called from
the change_state method, the queue2_mutex_lock is taken...

and _open_temp_location_file emits g_object_notify() which, when dispatch
properties is enabled, will try to get the value of that property, going
through queue2's _get_property() which grabs the same mutex

=> deadlock
