There's a couple of typos in the current version of the i18n/*.json files, which was causing my setup to fail whenever a query returned no rows:
i18n/en.json Line 12: replace "odbcdatacase-fetch-object-error" with "odbcdatabase-fetch-object-error" Line 13: replace "odbcdatacase-fetch-object-error" with "odbcdatabase-fetch-row-error"
i18n/qqq.json Same on lines 11-12.
