Fatal error: Unsupported operand types in includes/common.inc on line 1435

hello,
the error page displays when i try to edit a menu i created called "Menu". i was adding to this menu last night and it has been in development for weeks so i have no idea what happened here. the last thing i did before i noticed this error was install the webform module, though i have since uninstalled it, devel, cssinjector... anything trying to get rid of the problem. i've seen other posts about the Views module, but this is just menue, and only a menu i created. primary, secondary links, etc are fine. please help!
thank you,
dave

/**
* Format an internal Drupal link.
*
* This function correctly handles aliased paths, and allows themes to highlight
* links to the current page correctly, so all internal links output by modules
* should be generated by this function if possible.
*
* @param $text
* The text to be enclosed with the anchor tag.
* @param $path
* The Drupal path being linked to, such as "admin/content/node". Can be an
* external or internal URL.
* - If you provide the full URL, it will be considered an external URL.
* - If you provide only the path (e.g. "admin/content/node"), it is
* considered an internal link. In this case, it must be a system URL
* as the url() function will generate the alias.
* - If you provide '', it generates a link to the site's
* base URL (again via the url() function).
* - If you provide a path, and 'alias' is set to TRUE (see below), it is
* used as is.
* @param $options
* An associative array of additional options, with the following keys:
* 'attributes'
* An associative array of HTML attributes to apply to the anchor tag.
* 'query'
* A query string to append to the link, or an array of query key/value
* properties.
* 'fragment'
* A fragment identifier (named anchor) to append to the link.
* Do not include the '#' character.
* 'absolute' (default FALSE)
* Whether to force the output to be an absolute link (beginning with
* http:). Useful for links that will be displayed outside the site, such
* as in an RSS feed.
* 'html' (default FALSE)
* Whether the title is HTML, or just plain-text. For example for making
* an image a link, this must be set to TRUE, or else you will see the
* escaped HTML.
* 'alias' (default FALSE)
* Whether the given path is an alias already.
* @return
* an HTML string containing a link to the given path.
