Moving mail from-to folder hang Offlineimap ( Double IMAP repository )

Mon Oct 7 08:44:02 BST 2013

Hi.
I'm over new implementation of offlineimap with 2 IMAP server to be synced
bidirectional by using the local with thunderbirth, and remote with webmail.
This means that contents can be added, moved and deleted on any side of the
sync.....
All works fine on syncing, but when i move a message from a folder to
another ( or trash a message ), i get offlineimap error and continue to
duplicate the message before manualy delete ( purge ) over the 2 side the
moved message.
I attach an "offlineimap --info" and a dump of error.
Please help me.
Best regards.
