PHP Array To String Notice

I get the following notice on my webpage.

A PHP Error was encountered
Severity: Notice
Message: Array to string conversion
Filename: libraries/Template.php
Line Number: 3859

The line number 3859 is this:

	 return str_replace(LD.$name.RD, $value, $string);

Select allOpen in new window

<div class="controls">
{select id="bike_type"}
{if option_first_row}<option value="">Select a Value</option>{/if}
<option {selected} value="{option_value}" >{option_name}</option>
{/select}
</div>

The Notice goes away if I remove value="{option_value}".  It does not like the curly brackets.  How can I change this so it is okay with the curly brackets?

The following is the entire Method.  It is part of the Expression Engine CMS.  Maybe it can be defined in here someplace?

	function _parse_var_single($name, $value, $string)
	{
		// parse date variables where applicable
		if (in_array($name, (array) $this->date_vars))
		{
			return $this->parse_date_variables($string, array($name => $value));
		}

		// Simple Variable - Find & Replace & Return
		if (is_string($value))
		{
			return str_replace(LD.$name.RD, $value, $string);
		}

		//
		// Complex Paths and Typography Variables
		//


		// If the single variable's value is an array, then
		// $value[0] is the content and $value[1] is an array
		// of parameters for the Typography class OR an indicator of a path variable
		if (is_array($value) && count($value) == 2 && is_array($value[1]))
		{
			$raw_content = $value[0];

			// Make our path switches
			if (isset($value[1]['path_variable']) && $value[1]['path_variable'] === TRUE)
			{
				if (preg_match_all("#".LD."\s*".$name."=(.*?)".RD."#", $string, $matches))
				{
					$done = array();

					foreach ($matches[0] as $full)
					{
						if (in_array($full, $done))
						{
							continue;
						}

						$link = ee()->functions->create_url(ee()->functions->extract_path($full).'/'.$value[0]);

					//$single_quote = str_replace("'", '"', $matches['0']);
					//$double_quote = str_replace("'", '"', $matches['0']);

	//[0] => {id_path="about/test"}
	//[1] => "about/test"

					// Switch to double quotes

						$single = str_replace(array('"', "'"), "'", $full);
						$double = str_replace(array('"', "'"), '"', $full);

					//echo $single.' - '.$double.'<br>';
						$string = str_replace($single, $double, $string);
					//echo $string;
					//echo '<br>-----------------------<br>';

						$string = str_replace($double, $link, $string);

						$done[] = $full;

					}
				}

				return $string;
			}


			$prefs = array();

			foreach (array('text_format', 'html_format', 'auto_links', 'allow_img_url', 'convert_curly') as $pref)
			{
				if (isset($value[1][$pref]))
				{
					$prefs[$pref] = $value[1][$pref];
				}
			}

			// Instantiate Typography only if necessary
			ee()->load->library('typography');
			ee()->typography->initialize(array(
				'convert_curly'	=> (isset($prefs['convert_curly']) && $prefs['convert_curly'] == 'n') ? FALSE : TRUE)
				);

			$value = ee()->typography->parse_type($raw_content, $prefs);


		}

		if (isset($raw_content))
		{
			$this->conditional_vars[$name] = $raw_content;
		}
		//  SPOKE Modification.  I commented out the return.  It was causing a PHP Notice.  It is because it does not like any info inside of an option.
		 return str_replace(LD.$name.RD, $value, $string);
