Enabling the module kills my breadcrumbs.

Simply enabling this module causes the breadcrumb array to be empty.

I have done a bit of minor debugging. I know for sure that when I disable this module, my breadcrumbs appear. I enable the module, refresh the same page (with caching disabled) and my breadcrumbs disappear.

This happens before I even add any special menu items.

I have tried reinstalling the module, clearing the cache multiple times, rebuilding my menus and nothing seems to get my breadcrumbs back.

No matter where I print it from (various theme files and module hooks), the breadcrumb array returns empty.

When I have a spare moment later, I'm going to look at the module going and maybe do some debugging.

BTW, I don't see any php errors in my php log or watchdog, so I find this rather odd.
