Hi,

I've just set up fts-lucene and when I run searches on my inbox or when I run the indexer (doveadm index INBOX) I get the following segfault. I've run it multiple times and noticed that the data value is different each time so I guess it doesn't always crash at the same point.

I'm running dovecot 2.2.13-1 with clucene 2.3.3.4-8 on Arch Linux.

If you need any more information I'll be happy to help.

config:

2.2.13: /etc/dovecot/dovecot.conf

OS: Linux 3.15.2-1-ARCH i686

mail_location = mdbox:~/.mdbox mail_plugins = " fts fts_lucene" namespace { hidden = no inbox = yes location = prefix = INBOX. separator = . type = private } passdb { driver = pam } plugin { fts = lucene fts_autoindex = yes fts_lucene = whitespace_chars=@. } protocols = imap service auth { user = root } ssl_cert = </etc/ssl/my-certs/server.pem ssl_key = </etc/ssl/private/server.key userdb { driver = passwd } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep } protocol lda { postmaster_address = postmaster@server-speed.net }
