<pre>Looks like two different stack traces; perhaps two different bugs in a race
condition as to which will crash first?
Two of the backtraces show a crash in the wl_list_insert routine:
elm->next->prev = elm;
Tracing up the stack, this implies that:
new_output->destroy_signal.listener_list.prev->next
is invalid (e.g. maybe NULL).
Not sure what to make of that though. I think this will require more than just
a stack trace to sort out; perhaps instrumenting the
weston_view_assign_output() routine could reveal something?</pre>
