IMAP4 Message Head Incomplete?

Hi again,

When moving a message from a MBOX folder to a IMAP4 folder, 
using something like:

$mbox_folder->message(0)->moveTo($imap_folder);

I get this error:

---------------------------8<----------------------------------------
Method clone() is not defined for a Mail::Box::IMAP4::Head.

However, when I do a copyTo() instead, it works.
AFAIU, moveTo should be the same as copyTo plus a call to delete(),
right?

I also noted that IMAP4 is one of the few folder type that have a ::Head
package.  Other folders (like POP3, MBox) do not.

If try $imap_folder->message(0)->print it will fail because there is 
no $imap_message->head->print method defined.

So is it incomplete?!?
