"catchable error" when trying to view images in wp media library

[lorilin]

I just noticed yet another problem with the Church 4.0 theme.

I can upload and crunch images with the Flash uploader, and insert images into posts/pages. They appear just fine. But when inside the built-in Wordpress Media Manager I click "view," I get the following error:

Catchable fatal error: Object of class WP_Error could not be converted to string in path-to/tools/breadcrumbs.php on line 59

Any ideas about what's going on here and how I can fix it?

I'm running WP 3.0.1 and also have the DCG and NextGen gallery installed (deactivating them doesn't change anything).

Thanks in advance for any help!
