--- Comment #28 from Phillip Wood <phillip.wood at dunelm.org.uk> ---
Unfortunately while this fixes the MD5 metadata it breaks the vorbis comments.
There have been some reports that sound-juicer is extracting flac flies with
corrupted metadata recently[1,2], reverting the changes to gstflacparse.[ch] in
commit adeee44b fixes the problem with the vorbis tags. Here is the output of
metaflac --list showing the first and third metadata data blocks with
gst-plugins-good 1.12.3 and the same version with the changes to
gstflacparse.[ch] in commit adeee44b reverted
