Error in virtual mailbox dovecot 2.3-devel maybe in mailcount

[Jakobus Schürz]

Hi there!

I splitted my Mailarchiv to an extra namespace. Because i have some 
Problems with the Archiv.

I can open all Folders from Mailarchiv with dovecot. But i want to have 
a "all archives" Mailbox to search in all messages in only one virtual 
mailbox. Trying to open this virtual folder from thunderbird, I get in a 
big archiv this error in logs from dovecot:

and if i search the virtual mailbox with doveadm i get almost the same 
error. The "Broken mailbox_count_header" is missing there.

The full amount of emails in archiv is about 28000
