Duplicate emails when moving (OSE, Beta5)

[Amiba]

Hello
Recently I've installed the beta version of zimbra, and now, when moving, let's say, 10 emails with an IMAP client (tried it with Outlook and Evolution), I get 10 duplicate emails of the same message, instead of 10 different messages. When moving with the webclient, moving works correctly.
Is this a known bug of the beta version, or should I fill in a bug report?

hmmm
Do you have logs that indicate it's a problem with Zimbra?

Which logfile should I check?
As I mentioned, it happened when using evolution or outlook, and from different client machines, so I suppose it's not an e-mail client problem.
Thanks for the reply.
Cheers
