bug in indexer/indexer-worker

Hi,

I have already mentioned this in
http://www.dovecot.org/pipermail/dovecot/2014-November/098592.html

I could reproduce the errors above in a self-compiled v2.2.18 and the prebuilt
packages from xi.rename-it.nl (in addition to version 2.2.15 mentioned in the
link)

The problem occurs when enabling fts_tika in the plugins (tried tika 1.6, 1.7
and 1.8). I tried to move a folder of my mailbox with about 2000 mails to my
server (no users, modern hardware).
At some point I get an error and from this time on dovecot keeps repeating the
last lines with every mail that comes in ... see [1]
I then get kernel syslog messages like in [2]. when I try to index all users
(had another testuser) mailboxes with "doveadm index" I get the errors
of [3].

The mailfolder does contain mails with attachments of all sorts, videos, office
documents etc. When disabling fts_tika it works. dovecot -n output is [4]

Could someone of the devs please have a look?

best regards,
infoomatic
