Trying to edit the breadcrumbs for views using Custom Breadcrumbs module
The stable Drupal 7 version of Custom Breadcrumbs is currently in the 1.x branch; support for Views has only been added in the 2.x branch, for which there is no stable release for either version (there's an RC available for Drupal 6 but only a dev version for Drupal 7).

I think your options are:


Try the 7.x-2.x-dev branch and report any problems you find back to the module issue queue
Implement hook_preprocess_views_view() for your view and set the breadcrumb in there programatically (with code similar to the below).
Add custom PHP code to the header of your view (not advised):

$breadcrumb[] = l('Home','&lt;front&gt;');
$breadcrumb[] = l('View Name', 'path/to/view');
drupal_set_breadcrumb($breadcrumb);

A number of other 'hacky' methods that involve overriding the theme_breadcrumb function and making changes based on the path of a View (see this post for some examples).
