This sounds like a known issue [0] which has been reported several times, and

Knowing that this is case that pops up, I agree that we could do better around

I don't think adding more details is a bad idea, but it shouldn't require any
knowledge about internals so I think messages like the one below needs to be
reworded to be more helpful.
