Press releases needn't have issue taxonomy. Produces error log entry.

Line 10 of modules/features/openpublic_press_release/openpublic_press_release.theme.inc is

  $vars['content']['field_taxonomy_issues']['#theme'] = 'field_issues';

But a press release needn't have an issue, and when that happens, I see a watchdog warning 'Theme key "field_issues" not found.'

I suggest it becomes:

   if (isset($vars['field_taxonomy_issues'])) {
      $vars['content']['field_taxonomy_issues']['#theme'] = 'field_issues';
    }
