Using Dovecot 2.2.13 with Tika 1.5 on Centos 5 64bit

Tika is throwing an exception for some reason, which seems to be causing Dovecot's indexer to segfault. I'm using mdbox/gzipped compressed mail and private indexes for the shared folder. I'm importing mail via formail/dovecot-lda:

formail -s /usr/libexec/dovecot/dovecot-lda -d admin -m Public/TestSubFolder  < /tmp/Inbox.mbox

dovecot -n and the GDB backtrace are attached.

# find /var/mail/ -maxdepth 2
