It is usually much simpler if you provide e.g. a working minimal
example showing the issue, instead of explaining what the code does.

Maybe you need to define which is the thread-default main context as
soon as you create the new thread where the libqmi main loop is
supposed to run? See  g_main_context_push_thread_default(). Otherwise,
the g_signal_connect() you run may schedule the signal events in the
main context of the main thread, but you don't have a main loop
running there, right?
