It crashes in:
_CLTHROWA(CL_ERR_IllegalArgument, "language not available for stemming\n"); //todo: richer error
So looks like you're trying to use an unknown language. If you have only a single language, don't enable textcat. Or if you do, I guess you need to disable some languages that Snowball doesn't like.
Yet another possibility could be to use Dovecot's new lib-fts, which can also be used with fts-lucene. It's still basically the same snowball+textcat though, but made to work better. But looks like it's not documented yet in wiki..
