Actually I think I *have* run into the problem again, but this time it
seems to be related to my use of this plugin:
https://github.com/tlh/workgroups.el (in particular, C-x C-f from the
scratch buffer works before setting up a workgroup, but not after -- after
it complains about the minibuffer being active).

I'm going to try not using it for a few days to see if there are any other
issues.
