Original commit message from CVS: 2004-02-25 Andy Wingo <wingo@pobox.com> * gst/interleave/interleave.c (interleave_buffered_loop): Always push only when channel->buffer is NULL. Prevents segfaults doing the state change after a nonlocal exit, like a scheme exception. * gst/audioconvert/gstaudioconvert.c (gst_audio_convert_getcaps): Handle the case where the intersected caps is empty.
