I'm having the same problem (above mentioned warning) with 5.x-3.0 running Drupal 5.14. It exists in all nodes in which I'm using location. When I try to change a location the address updates but the lat/long coordinates do not recalculate and are blank. I used the "delete" box to clear the previous location before inputting the new one. Clearing cache...reinstalling module have no effect.

I got the same problem. Then I opened the edit page for the content type that uses location, and re-submit the content type setting. After that, when I opened the edit page of the nodes of that content type, I saw no more of this error message.

I found a solution at http://drupal.org/node/36408

PHP5 is the problem. I wouldn't have thought of that because I've never used PHP5, but a quick look into the PHP manual reveals that "The behavior of array_merge() was modified in PHP 5". Read Example 3 at http://us3.php.net/manual/en/function.array-merge.php

As a result of this hint, I modified location.module line 1387 (at least that's the line in my modified location.module) to read something like this (extra lines for the complete function listed for context.)

/**
 * Returns an empty location object based on the given settings.
 */
function location_empty_location($settings) {
  $defaults = location_invoke_locationapi($location, 'defaults');
  if (isset($settings['form']['fields'])) {
    foreach ($settings['form']['fields'] as $k => $v) {
      $defaults[$k] = array_merge((array)$defaults[$k], (array)$v);
    }
  }

The only change is the addition of (array) before each parameter in the call to array_merge on line 1387. That got rid of the error message and I'm presuming that this has fixed the issue and it is not silently failing.
