I have tracked down the problem to this function:

/**
 * Generate image derivatives.
 */  
function _image_build_derivatives(&$node, $temp = FALSE) {
  // sanity check:
  if (!_image_check_settings()) {
    return false;
  }
  $info = image_get_info(file_create_path($node->images['_original']));
  $sizes = _image_get_sizes();
  if (!$temp) {
    _image_remove($node);
  }
  foreach ($sizes as $size) {
    if ($size['label'] && $size['width'] && $size['height']) {
      if ($info['width'] > $size['width'] || $info['height'] > $size['height']) {
        $source = file_create_path($node->images['_original']);
        $destination = _image_filename(basename($source), $size['label'], $temp);
        if (!image_scale($source, file_create_path($destination), $size['width'], $size['height'])) {
          drupal_set_message(t('Unable to create %label image', array('%label' => $size['label'])), 'erro$
        }
        else {
          $node->images[$size['label']] = $destination;
          if (!$temp) {
            _image_insert($node, $size['label'], file_create_path($destination));
          }
        }
      }
      else {
        $node->images[$size['label']] = $node->images['_original'];
      }
    }
  }
}

And in particular this line:

        if (!image_scale($source, file_create_path($destination), $size['width'], $size['height'])) {
          drupal_set_message(t('Unable to create %label image', array('%label' => $size['label'])), 'erro$
        }

I can't, for the life of me, find any function called image_scale(), but it's clearly failing.

Does anyone know where this function lives?

I'm trying to prove to my boss that we can use this NOW, but I need to get the preview up and running today.

I forget where the function is, but it ends up calling the convert function in /includes/image.imagemagick.inc.

I had the same problem, and tracked it down to the lines:

function _image_imagemagick_convert($source, $dest, $filter) {
  $convert_path = variable_get('image_imagemagick_convert', '/usr/bin/convert');

in /includes/image.imagemagick.inc

For some reason, it was getting a blank value. I set it in the database, but still it did not work.

I just changed it manually to:

function _image_imagemagick_convert($source, $dest, $filter) {
  $convert_path = variable_get('image_imagemagick_convert', '/usr/bin/convert');
$convert_path="/usr/bin/convert";

This is not a good solution, but it'll make it work for now....
