I don't pretend to understand it, but I can tell you that both ends
look alike, apart from the first and last couple of lines.
Here's the end of it. You'd have to unwrap the lines to see anything.

I think it would be too much work to do this. I don't have the time,
knowledge or energy to work out which library might be failing. It's
very probably that the problem is with my setup or of my doing. If not,
someone else will have to find and analyse it. I know that's not how
Free software is meant to work, but reality intrudes.
