I've been seeing such bugs for years now.
I've sprinkled such assertions at many more places in the hope to better
track the source of the problem.  I did find one such source and fixed
it a couple years ago, but it still happens.
Generally both windows are non-nil and one of the two is the
minibuffer-only frame.
