Indexing failing with Xapian InvalidArgumentError: Empty termnames aren't allowed.

[paulspringett]

After upgrading to Xapit 0.3.0 (from 0.2.7) I get an InvalidArgumentError (from xapian) when running rake xapit:index

I have run

$ rails g xapit:install

My model xapit method looks like this:

xapit do
  text :name
end

(where name is an active record column)

Stacktrace:

$ bundle exec rake xapit:index --trace
** Invoke xapit:index (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute xapit:index
rake aborted!
InvalidArgumentError: Empty termnames aren't allowed.
