Fatal error: Unsupported operand types in common.inc on line 1598

Hi.

Conditions.
User accounts was not available to view by anonymous users. LoginToboggan "Present login form on access denied (403)" option was enabled. I tried to access user/1 page as anonymous.
I got "Fatal error: Unsupported operand types in common.inc on line 1598".

I found the reason. This was happen, because LoginToboggan set $_GET['q'] = "user" in logintoboggan_denied() function.

In menu_get_active_breadcrumb() function Drupal check active path for access and (as "user" is normal accessibility drupal path) start to render breadcrumbs.
But menu_get_active_trail() function was run before and $trail was cached in static variable, which contain disallowed path ("user/1").

Drupal menu system not create localized_options for item array, which access denied.
So, drupal render breadcrumbs from trail, which contain item without localized_options, which must be passed to l() function (see menu_get_active_breadcrumb()).

This issue not appear on clean drupal installation. But, may cause with another modules that uses menu_get_active_trail() function (ex. context module).

I'm attached patch for 6.x-1.7 version.
Not sure, that this is best way for fix that problem. But I'm too tired by catching that bug.
