But that's not how the code is written:

g_task_run_in_thread(obj->task, custom_object_work) ->
  custom_object_worker() ->
     signal_emit() ->
        g_idle_add_full(..., signal_emitter, ...);

signal_emitter() is the function that *actually* emits the signal.
signal_emitter() is supposed to be running in the main context thread
by the virtue of being the g_idle_add_full() callback.

Are you saying that the g_idle_add_full() callback also runs in the
worker thread?
