<pre>There seems to be a race between a client disconnecting and the text protocol
attempting to post an event to the dying client resource via
wl_text_input_send_language(...). Various backtraces indicate that the
resource is not always completely destructed before it reaches
wl_resource_post_event(...), but ultimately results in a segmentation fault.
See attached backtraces for more evidence of this issue.

The only existing test case, so far, that reproduces this issue is the
efl/shm/EntryCutTest in wayland-fits. Nonetheless, this appears to be a core
issue unrelated to efl.</pre>
