I can easily reproduce such an error here.  Do you have a boxed mode- or
header-line, or anything that makes these lines higher or lower than an
average normal line?

I'll check in a fix for this soon, but I still see a related bug whose
cause I wasn't able to identify yet.

This sounds strange.  Paul, how can such a thing happen?
