My recipe was an example of "command from a buffer which is not in a
project".  Here's a recipe for the issue using C-x p p:

1. (setq project-switch-use-entire-map t)
2. Be in a buffer in project A
3. C-x p p b to switch to project B and select a buffer in project B
4. Type a buffer name which doesn't exist
5. The resulting buffer is in project A, not B
