Sometimes I see this when a buffer is open to a file that has never been
saved. This can happen when I start a new org file and try to do some
agenda thing before I save it, or when some function/process opens an
org-file in a new directory for example, and an agenda thing happens before
it has been saved.

You could check to see if there is a refile.org buffer open (not
necessarily to the existing file, just one named refile.org) but that has
not been saved. I don't know why such a buffer would be open, but if it is,
it might be a cause of that problem.
