AccurateRip disagreement between initial rip and image verify

[pmoris]

A number of successful rips (as reported by whipper's log) fail during image verification when run immediately afterwards.

I ripped and verified the CD twice and can confirm all outputs are identical (md5sum of the flac files also matches). CUETools also reports the rips as being accurate.

I just finished ripping a large part of my collection and only a handful CDs showed this problem.

Tested using the whipper v0.10.0 docker image.

What does the DB column represent? Because that's the part that seems to differ between the rip and verify log.

Potentially related to these older issues? #339, which supposedly is a duplicate of #239, but the latter seems different from what I'm reporting here, since the initial rip proceeded without any problems.
