I've fixed at least the last part, so the major mode of the re-created
*scratch* is now as expected.

Martin, I'd appreciate your views on the changeset in commit
89f54e8157 and regarding the original problem to begin with.
Basically, set-window-configuration was called in a situation where it
has only one valid buffer to play with, which is tough for its logic
and the various other functions it invokes.  The result was a bunch of
bad windows with nil as their buffer.
