warning: implode() [function.implode]: Bad arguments. in asin.module on line 206.

I believe the fix discussed in Error in asin.module on line 205 (http://drupal.org/node/126436) inadvertently introduced another issue. Since updating to 1.4, ASIN has been throwing an implode error:

warning: implode() [function.implode]: Bad arguments. in PATH/asin.module on line 206.

After reviewing the 1.4 changes and the above issue, it looks to me like the object name was switched mid-line from $product to $asin. In 1.4, lines 205 - 208 read thus:

      if (!empty($product->author)) {
        $output .= '<p class="asin-author">by '. is_array($product->author) ? check_plain(implode(', ', $asin->author)) : check_plain($asin->author) .'</p>';
      }

Those $asin->author calls are the trouble. I believe they should read $product->author.

      if (!empty($product->author)) {
        $output .= '<p class="asin-author">by '. is_array($product->author) ? check_plain(implode(', ', $product->author)) : check_plain($product->author) .'</p>';
      }

That change is resolving the problem in our environment.
