Subject: [PATCH] Copy over r54544 from trunk:

  If the uncompression buffers are empty, they have no data; set the count
  of bytes in them to 0, as there's no data in them, and set the offset in
  that buffer of the stream's current position, to 0, as we're currently
  at the beginning of the file in both streams.

  This fixes some tricky-to-reproduce errors (which show up only if the
  ngsniffer_t structure is allocated from data that's been allocated,
  written to in those variables, and freed).
