How to fix Zen theme only showing correct breadcrumbs with theme developer module enabled?
So, apparently there is a conflict between the Path Breadcrumb module and zen's built in breadcrumbs. When the Path Breadcrumb module is enabled, the zen breadcrumb doesn't append the title to the path. I'm assuming that Path Breadcrumb hooks into and overrides the drupal_get_breadcrumb(), although I haven't been able to demonstrate this myself. When I disable Path Breadcrumb, the zen breadcrumbs behave normally. This leaves me with two viable options: 1) hack the current status of the theme breadcrumbs, 2) or code Path Breadcrumbs for the rest of my pages. Neither options seems particularly palatable.
