OpenID Plugin (WP 2.5) produces implode() “Bad Argument” error

Line 387 produces an “Bad Argument” error from the implode() function. The variable being imploded is actually a string on my computer.

To fix this error, replace this:

if(isset($curl_version['protocols']))
				$curl_message .= 'Supports: ' . implode(', ',$curl_version['protocols']) . '. ';

With this:

if(isset($curl_version['protocols']))
				if(is_array($curl_version))
					$curl_message .= 'Supports: ' . implode(', ',$curl_version['protocols']) . '. ';
				else
					$curl_message .= 'Supports: ' . $curl_version['protocols'] . '. ';
