User warning in mailarchive_cache module after cron executes

I'm guessing this shows up for each taxonomy created for mailarchive (I have two) but I'm not really sure whats going on here.

I can't execute the query manually

DELETE cache_mailarchive_overview WHERE dirty = 1 AND timestamp < 1250115488

I believe it's missing FROM, to successfully clear caching, so should be:

DELETE FROM cache_mailarchive_overview WHERE dirty = 1 AND timestamp < 1250115488

Error displayed as:
