I agree, but I am using the ubuntu packages as provided by yourselves 
(not Ubuntu's). I'm guessing this must be some kind of linking/packaging 
issue as I have been using your packages for some years now and have not 
seen this particular error before. It only started appearing after I 
upgraded to 2.3.7 on July 19th.

All my executables in /usr/lib/dovecot/ are stripped so I cannot check 
my versions.
