protect g_object_notify() calls with an existing mutex

I haven't studied the problem carefully, so I don't know what happens if a
handler for the notify signal tries to invoke a method on the input-selector
instance given the mutex being held with g_object_notify() is called. 
Hopefully it doesn't lock up.

I'm sure the non-thread-safety of g_object_notify() is a big deal, so maybe
there's a proper "standard" solution to this like some kind of global glib
mutex or something.

Anyway, this patch stops the example script stop segfaulting.
