dovecot - Feb 2011 - dsync conversion error

Hello
When converting mailboxes I get that kind of error messages :

dsync(xxx): Error: Next message unexpectedly lost from mbox file 
/user/xxx/mail/Sent at 9580036 (cached)

the dsync command I run is

dsync -u xxx mirror mbox:/user/xxx/mail:INBOX=/var/mail/xxx

Dovecot mail_location configuration is :

mail_location = 
mbox:~/MailSpace/Mailboxes:DIRNAME=Mbox-Messages:INDEX=~/Index:CONTROL=~/Kontroll

Note that ONLY  happen on users's "Sent" folder,  never on any
other folder

Thanks for any advices.

This fixes itself automatically, so I don't think you should worry about
it much. And it's not a problem with dsync, the same thing would happen
if e.g. IMAP client would try to fetch all of the message bodies.
Originally the problem was probably caused by buggy mbox code.
