after two of those errors ends up in a segfault.

I fixed it by setting priv->decoders to NULL after freeing this list.


The issue appeared after :

    Use g_slist_free_full()


The previous code was doing :
       while (priv->decoders) {
               g_object_unref (priv->decoders->data);
               priv->decoders = g_slist_delete_link (priv->decoders, priv->decoders);
       }
=>  priv->decoders = g_slist_delete_link (priv->decoders, priv->decoders); was setting the list to NULL as the last item was NULL and ended up assigned to priv->decoders.
