Call to undefined method UpdateQuery::values() in location/location.module on line 929

There appears to be a mistake starting on line 927 of location.module. Specifically, values() is not a valid method.

db_update('location')
->fields(array('latitude', 'longitude', 'source'))
->values($location)
->condition('lid', $location['lid'])
->execute();
}

The fields() method is supposed to accept an associative array of keys and values. I believe it should be more like this:

db_update('location')
->fields(array('latitude' => $location['latitude'], 'longitude' => $location['longitude'], 'source' => 0))
->condition('lid', $location['lid'])
->execute();
}

In the end, I had to manually enter the coordinates of my locations rather than let JIT encoding handle them, so this fix didn't work for me, but I suspect it was due to Google not responding to geocoding requests from my IP (it's happened before). Hopefully this puts someone on the right path to fixing the error.
