dovecot - Jan 2019 - Error with virtual index "Broken mailbox_count header"

Hi, we experience trouble with one of our virtual mailboxes.

dovecot-virtual:

`
*
-INBOX/Trash
-INBOX/Spam
     all
`

Error log:

```Error: virtual index 
/var/vmail/mailboxes/kirchhofer.net/tobias/virtual/all: Broken 
mailbox_count header```

This happens only with the filter form above. All other virtual 
mailboxes works fine.

Jakobus Sch?rz experienced something similar:

We do not have the panic message.

Is this probably something on our side or is this Dovecot?


```
namespace virtual {
   prefix = Virtual/
   separator = /
   location = virtual:~/virtual
}
