How to fix Zen theme only showing correct breadcrumbs with theme developer module enabled? I've been going around in circles with trying to get breadcrumbs working as the client wants them on a Drupal 7 site with a custom Zen theme working. I've built the site out and it requires the titles being added to the breadcrumb trail.

The issue is, the crumbs only display correctly with the theme developer module enabled. I know you can set the Zen theme's settings to append content titles to the breadcrumb trail, but this doesn't seem to work (either through specifying through the UI, or by changing the settings in the MYTHEME.info file). They do however correctly display with the theme developer module enabled. For a host of reasons I can't have a live site with this module enabled.

So,


1) How do I get the breadcrumbs working properly and why doesn't it work through the UI or in code?
2) How can I resolve this apparent conflict?
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.
