Hi Karl,
it seems the primary problem is that pdftex tries to set font expansion parameters for a font without checking if the font has been successfully loaded (hence it modifies null_font which is totally wrong).
Please find the proposed patch attached. I have tested it against your test files (thanks again for making things easy to reproduce). But shouldn't there be some message then too?
