i'm using a build of the master branch of mixxx built with faad=1 on ubuntu 19.04

here's an example of a before file:
https://igor.moomers.org/public/linger-before.ogg
here is the output of ogginfo on that file:

Processing file "the cranberries/the cranberries - linger.ogg"...

Total data length: 4430771 bytes
Playback length: 4m:34.809s
Average bitrate: 128.984635 kb/s
Logical stream 1 ended

i open mixxx -- note that "track metadata synchronization" is enabled.
i then load the file onto a deck.
i then press play. i let it play long enough that the played counter increments
i then stop the track and exit mixxx

the resulting file is here:
https://igor.moomers.org/public/linger-after.ogg
the output of ogginfo on the updated file:
WARNING: Could not decode Vorbis header packet 1 - invalid Vorbis stream (1)
WARNING: Could not decode Vorbis header packet 1 - invalid Vorbis stream (1)
Vorbis stream 1:
Total data length: 0 bytes
Playback length: 0m:00.000s
Average bitrate: -nan kb/s
Logical stream 1 ended

re-opening mixxx and trying to play the file again says "the file could not be loaded", with the following log output:
Warning [CachingReaderWorker 1]: SoundSourceOggVorbis - Failed to initialize decoder for "file:///home/igor47/Music/music/the cranberries/the cranberries - linger.ogg"

this doesn't seem to happen with all ogg files, but a good number of them.

as a workaround, disabling metadata synchronization works well.

i'm glad i had backups of my ogg files, i haven't found a way to fix them once they're corrupted.

This is supposed to be caused by a severe bug in TagLib 1.11.1 and will affect all platforms:

taglib/taglib#864

Unfortunately TagLib haven't released a bug fix version yet.

Our only option to prevent any further damage is to disable metadata export for OGG files until fixed versions are available for ALL platforms!
