The address of the structure remains constant (that is, display_line is
called with the same pointer). I don't know if this is expected to
change or not. I didn't actually compare the contents between calls.

This is hard to do. I tried to simply copy the text to another buffer in
trying to reproduce the problem, but I couldn't. It might be due some
overlays or properties.
Is there some way to conveniently dump the entire buffer state to a file
so we can debug this by reloading the content without having the mail
client in the way?
There's a lot of customization in the way which is making this harder
than it should be.
