The "Define" and "Spell" keywords cause Alfred 1.2 to crash on macOS Sierra

If you're using Alfred 1.2 from the Mac App Store, you may find that the "define" and "spell" Dictionary keywords cause Alfred to crash on macOS Sierra.

We recommend upgrading to the current version of Alfred, which is available to download free directly from alfredapp.com, and is actively supported on recent macOS versions, as well as much more featureful.

If you are on macOS Sierra or above, and prefer to stay on Alfred 1.2, we recommend disabling the spell/define feature.
