Array to string conversion ... Possible PHP 5.3 Bug?

Sorry, I didn't notice the error was in a core file.

Is there a way to get a stack trace, so I can see the caller?

Line 941

function t($string, $args = array(), $langcode = NULL) {
...
    return strtr($string, $args); // line 941
...
}

Function

function t($string, $args = array(), $langcode = NULL) {
  global $language;
  static $custom_strings;

  $langcode = isset($langcode) ? $langcode : $language->language;

  // First, check for an array of customized strings. If present, use the array
  // *instead of* database lookups. This is a high performance way to provide a
  // handful of string replacements. See settings.php for examples.
  // Cache the $custom_strings variable to improve performance.
  if (!isset($custom_strings[$langcode])) {
    $custom_strings[$langcode] = variable_get('locale_custom_strings_'. $langcode, array());
  }
  // Custom strings work for English too, even if locale module is disabled.
  if (isset($custom_strings[$langcode][$string])) {
    $string = $custom_strings[$langcode][$string];
  }
  // Translate with locale module if enabled.
  elseif (function_exists('locale') && $langcode != 'en') {
    $string = locale($string, $langcode);
  }
  if (empty($args)) {
    return $string;
  }
  else {
    // Transform arguments before inserting them.
    foreach ($args as $key => $value) {
      switch ($key[0]) {
        case '@':
          // Escaped only.
          $args[$key] = check_plain($value);
          break;

        case '%':
        default:
          // Escaped and placeholder.
          $args[$key] = theme('placeholder', $value);
          break;

        case '!':
          // Pass-through.
      }
    }
    return strtr($string, $args); // line 941
  }
}

well, i coulda guessed.

wasn't sure if that would give me all i needed.

thanks.
