On the list of Pages, clicking to Edit a particular page redirects to the list of trash

I traced the problem to what must have been a fluke in the autosaves for that page. Once I deleted the autosaves, I was able to edit the page. In reviewing the core code, I didn’t see anything that would cause the function to redirect to the listing of pages in the trash. FWIW, the post_name name column looked like this before the delete:

6609-revision-v1               
6609-revision-v1               
6609-revision-v1              
6609-revision-v1               
6609-autosave-v1               
6609-autosave-v1             
6609-revision-v1
