Breadcrumbs and All-In-One Event Calendar

Hi Time.ly,

Is there a way to show page breadcrumbs for the calendar single events?

I have tried using Yoast’s SEO plugin to do it, using this code:

<?php if ( function_exists('yoast_breadcrumb') ) {
	yoast_breadcrumb('<p id="breadcrumbs">','</p>');
} ?>

as well as this code for Breadcrumb NavXT:

<p class="breadcrumbs">
    <?php if(function_exists('bcn_display'))
    	 {
    bcn_display();
     }?>
</p>

Neither works. It’s just blank. I know the function works, because if I add
echo 'WUT!!';
into the function for either one, it will output. But… no breadcrumbs.

Breadcrumbs work on every other page and post type, with either one.

Thanks~
