gst/matroska/matroska-mux.c: Don't strcmp() NULL strings.
Original commit message from CVS: * gst/matroska/matroska-mux.c: (gst_matroska_mux_stream_is_vorbis_header), (gst_matroska_mux_write_data): Don't strcmp() NULL strings. Only start new clusters on video keyframes, not on any random audio buffer that doesn't have the DELTA_UNIT flag set (fixes 'make check' again).
