dovecot2 broken on 6.99.40

Hi,

Sorry if this is not the right list. I prefer to post here before posting to 
dovecot mailing list. 

So, on a 6.99.40 from yesterday (and also with a 6.99.35), dovecot2 fails with:

Apr 15 14:42:16 mailsrv dovecot: auth: Error: BUG: Authentication client sent 
unknown handshake command: 
REQUEST?3350593537?422?1?2534ef156b4cf36aa05842b5595add1d?session_pid=392?req...

The same dovecot binary was running fine on 6.99.32 (I only change the kernel).

Any idea ?

Thanks you.

Best,
jym
