offlineimap IMAP<->IMAP crash

[Mathias Bertelsen <mathiasb@xxxxxxxx>]

I am syncing two IMAP mailboxes and that leads to a crash:

...
Copy message 814 IMAP[INBOX.Archive.2004] -> MappedIMAP[INBOX.Archive.2004], 
LocalStatus[INBOX.Archive.2004]
Copy message 815 IMAP[INBOX.Archive.2004] -> MappedIMAP[INBOX.Archive.2004],

This is my .offlineimaprc :

[general]
accounts = movethere
ui = Noninteractive.Basic, Noninteractive.Quiet

[Account movethere]
localrepository = remotehost
remoterepository = localhost

[Repository remotehost]
type = IMAP
remotehost = remotehost.org
remoteuser = username
ssl = yes
remotepassfile = somefile

[Repository localhost]
type = IMAP
remotehost = localhost
remoteuser = username
ssl = yes
remotepassfile = somefile

localhost is a courier-imapd 4.0.1
remotehost is a cyrus-imapd 2.1.18-1

Any help would be appreciated?

:)
