dovecot - Dec 2014 - dsync "Error: imapc: Remote server didn't send BODY for UID"

Anyone know what this means and what the implications are?  Does this 
mean some messages are missing?

$sudo dsync -D -v -f -R -o mail_fsync=never backup -u test imapc:
...
dsync(test): Error: imapc: Remote server didn't send BODY[] for UID

Hippogriff:  An animal (now extinct) which was half horse and half
griffin.  The griffin was itself a compound creature, half lion and
half eagle.  The hippogriff was actually, therefore, only one quarter
eagle, which is two dollars and fifty cents in gold.  The study of
zoology is full of surprises.
