custom_breadcrumbs give warning message when location / location_cck is installed

When I create a custom breadcrumb (as in any custom breadcrumb) I get the following error (on the content type with the custom breadcrumb):

warning: array_filter() [function.array-filter]: The first argument should be an array in W:\www\ drupal\sites\all\modules\location\contrib\location_cck\location_cck.module on line 385.

warning: array_keys() [function.array-keys]: The first argument should be an array in W:\www\drupal\sites\all\modules\location\contrib\location_cck\location_cck.module on line 385.

warning: Invalid argument supplied for foreach() in W:\www\one-earth.com.d6\sites\all\modules\location\location.module on line 1440.

Any hints?

Should I just report this on the custom breadcrumbs issue queue?
