emotion_object_init() is called. Hence, setting sd->video to NULL
there implied that the code:
emotion_object_init(o, module);
emotion_object_file_set(o, file1);
emotion_object_file_set(o, NULL);
emotion_object_file_set(o, file2);
seg fault.
(such code is useful when you want to reset the same stream
(file1 = file2). The other solution would be to destroy everything
and recreating the pipeline, which is not nice)
