Original commit message from CVS:
* gst/base/gsttypefindhelper.c: (helper_find_peek),
(gst_type_find_helper):
The memory returned by gst_type_find_peek() needs to
stay valid until the end of a typefind function, and
typefind functions may keep results from different
offsets around, so we can't just unref the buffer from
the previous _peek(), but have to save all buffers
returned by _peek() until typefinding is done and only
free them then.
