According to the gstreamer docs [1], the GstMessage pointer returned by gst_bus_pop() is nullable, meaning NULL is a valid return value. Previously, gst_is_missing_plugin_message would throw an assert when its message object parameter would fail the GST_IS_MESSAGE macro check, crashing the entire process (unless running in a try-catch block of course). Instead of relying on valid messages, check if the message object itself is valid before passing it to other gstreamer functions.
