Normal VMs :) In app_voicemail.c this, IMHO, is where it is performing the
search for IMAP stored messages:

pgm = mail_newsearchpgm ();
                hdr = mail_newsearchheader ("X-Asterisk-VM-Extension",
(char *)(!ast_strlen_zero(vmu->imapvmshareid) ? vmu->imapvmshareid :
mailbox));
                hdr->next = mail_newsearchheader("X-Asterisk-VM-Context",
(char *) S_OR(context, "default"));

and that is contained within proc __messagecount().  If no VMs are there
then I see why msgcount + 1 would be used to increment from zero too one. 
Yet if one has already been left then why would msgcount be two already ?
That is the mystery and I do not know enough 'C' to be able to work out the
code :(  Anything I can do to help I will as this is causing our clients
quite a bit of pain.  I did raise it with Zimbra support who checked their
IMAP code and came to the same conclusion something was happening on the
Asterisk side :- http://bugzilla.zimbra.com/show_bug.cgi?id=46704
