Panic when using doveadm fts lookup

[André Rodier]

Hello,

I am actually testing dovecot fts search, using doveadm fts lookup.

I run this command:

doveadm fts lookup -u andre subject "Test"

And this generate this error:

doveadm(andre): Panic: file mail-storage.c: line 1694 
(mailbox_get_open_status): assertion failed: (box->opened)
doveadm(andre): Error: Raw backtrace:

Do I have to do anything special to test the dovecot fts index with 
doveadm lookup? I have not found the documentation on the dovecot web site.

Thanks for your advices.
