Caroline, what is the extent of this content type? How many lists is it active on and how many pages might be present?
I've hit this before when content types were created at the list level during development before being converted to a feature for development. Was content migrated by any chance? Anyway, steps we used to fix follow. Someone may recommend alternatives or correct some steps. Once you've located all the Page libs where the content type is present you'll need to: 1. Publish a major version of all pages. 2. Disable check-out, versioning and any approval workflows on the library. 3. Change all pages to use a different content type (and associated layout page if a custom one is present). 4. Delete the problematic content type from the list. 5. Add it back again from the "Add from existing site content types" link. 6. Try to create a new page from the content type. If you're successful then you can change the content type back on all the pages. 7. Re-enable check-out and versioning. There's probably a way to do this programatically or with PowerShell but someone else would have to help with that. :) You may also hit problems with previous Page versions still using the content type.

Which is just what you are saying would happen.

When that happens, trying to deploy content types as part of a feature will fail with the error you described - even if your feature does not have the conflict itself - its enough that there is a conflict in the site. I need to report this to MS...

It occurs when I try to create a new page that uses a particular page layout. I have not had anything to do with developing the site, so I don't know if any manual changes to content types have been made. Can anyone recommend a good place to starting looking to find a resolution to this?
