Original commit message from CVS: * gst/playback/gstplaybasebin.c: (gst_play_base_bin_init), (gen_preroll_element), (remove_groups), (setup_subtitle), (gen_source_element), (setup_source): * gst/playback/gstplaybasebin.h: Multiple .sub files is just a stupid idea... Fix some threading mistakes. Interestingly, external .sub files cause playbin to hang, I don't know why... Parsing fixes contributed by Felix Kooman <fkooman@tuxed.net>.
