Any Ideas?

It seems that you have somehow been able to create invalid data in category/catalog-node tables.
Are you using RC2 or RC3?

If you go to Catalog -> Orphaned Items do you see any orphaned products or categories?

I think it is something like Sohaib says. I had remembered getting a similar message in the past and it was after I had put some data into the tables directly, but I couldn't remember exactly what I had done.

This was a new install. I believe it is RC3. I had attempted to install numerous times and was unsuccessful. I finalyy created a new database and completely reinstalled and all is OK. Luckily I did not have much into it.

I had attempted to install numerous times and was unsuccessful.

Multiple attempts would have created the database records multiple times.
