"Collections" admin tab not working, SimplePages the culprit?

I've just upgraded to 1.5.2 from 1.4 and I'm having trouble with the Collections tab in the admin view. I enabled error reporting and debugging. When I click Collections, I get this message:

Omeka has encountered an error</p>

What problems exactly would SimplePages be causing, as suggested by the first error message? I had the plugin installed previously before upgrading, and I downloaded the latest version (1.3) and upgraded.

Does deactivating Simple Pages make this problem go away?

In fact it does! But I need my SimplePages :)

This is a little odd...

Do you happen to have a simple page called "collections" or something similar?

Yes in fact I *did* have a Simple Page called "collections"! I just changed the slug to digitalcollections and it works now! Thanks so much for your suggestion. Weird that this bug cropped up in 1.5.2 but not in 1.4. How would I go about reporting that, or is it too insignificant to bother with?

I've gone ahead and created an issue for this problem.

I'm thinking this resulted from the SimplePages upgrade, not the Omeka one.
