Empty dictionary file when creating text search dictionary

Found this a couple of weeks back and just re-tested against head:

CREATE TEXT SEARCH DICTIONARY with an empty thesaurus file will crasch
the backend.

To reproduce:
$ echo "" > $(pg_config --sharedir)/tsearch_data/thesaurus_empty.ths

Then use this thesaurus to create a text search dictionary:
CREATE TEXT SEARCH DICTIONARY thesaurus_astro (
TEMPLATE = thesaurus,
DictFile = thesaurus_empty,
Dictionary = english_stem
);

It doesn't matter if the file is compleatly empty or just have comments.
The result is the same.
Add a word:
$ echo "foo: bar" >> $(pg_config
--sharedir)/tsearch_data/thesaurus_empty.ths

Creating the dictionary will now work.

Sorry I have no patch to attach.

This is a duplicate report and has been fixed by Tom already.
