[Flac-dev] problems with flac?

So I recently encoded my entire CD collection (over
7000 songs) to flac and I have found that 18 of them
have a strange problem. The files are corrupted in
some way.. They will stop playing abruptly in the
middle of the song. I've attached a listing of the
metadata and you'll see what I mean.
You can see that the seek points toward the end have a
bunch of zeros and I'm not sure how they got there.
The 18 songs that exhibit this problem are some of my
longer tracks, but not all my long songs have this
problem. I honestly can't confirm if the original
ripped wav was corrupted or not since it has been
converted to flac! But the CD's play fine and
subsequent ripping works fine.
Any explanations as to why the data looks this way?
