When a listener makes changes to a the thing it listens to, it typically will want to have g_signal_handlers_block_by_func()/g_signal_handlers_unblock_by_func() around the piece of code that does the change, and/or "if (new_value == current_value) return;" at the beginning of the callback to prevent the pingpong you are describing. Sometimes it's tricky to get this right.
