Ronald S. Bultje e3a0b57b75 ext/gnomevfs/gstgnomevfssrc.c: Some debug. 
Original commit message from CVS:
* ext/gnomevfs/gstgnomevfssrc.c: (gst_gnomevfssrc_get),
(gst_gnomevfssrc_srcpad_query), (gst_gnomevfssrc_srcpad_event):
Some debug.
* gst/avi/gstavidemux.c: (gst_avi_demux_reset),
(gst_avi_demux_handle_src_event), (gst_avi_demux_read_superindex),
(gst_avi_demux_read_subindexes), (gst_avi_demux_add_stream),
(gst_avi_demux_stream_index), (gst_avi_demux_skip),
(gst_avi_demux_sync), (gst_avi_demux_stream_scan),
(gst_avi_demux_massage_index), (gst_avi_demux_stream_header):
* gst/avi/gstavidemux.h:
Support for openDML-2.0 indx/ix## chunks. Support for broken index
recovery (where, if part of the index is broken, we will still read
the rest of the index and recover the broken part by stream
scanning). More broken media support. EOS workarounds. General AVI
braindamage headache recovery. Aspirin included.
