+Subject: [PATCH 03/48] screen-cast-stream-src: Don't leak GSource
+
+For every stream src, we created and attached a GSource. Upon stream
+src destruction, we g_source_destroy():ed the GSource. What
+g_source_destroy() does, hawever, is not really "destroy" it but only
+detaches it from the main context removing the reference the context had
+added for it via g_source_attach(). This caused the GSource to leak,
+although in a detached state, as the reference taken on creation was
+still held.
+
+Fix this by also removing our own reference to it when finalizing.
