Meaning of this error message

[lyapounov]

Hello !

I have this message while scanning, and I am not sure to understand, and if it is important :

FLACDecoder: FindSync LOST_SYNC: 0 at offset 10346046 in 6) Jazz/John Coltrane/Blue Train/00-01-Blue_Train.flac

Not while playing, but at the end of the scan process, right after the message which says minimserver is running..

(PS I just realized I have posted already this message in 2016 :-(

Thx !
Best
