Just a potential suggestion for the OP: maybe change the line-width
attribute to e.g. "(1 . 1)" instead of 1 as all of the faces I have
customised (using customize-face) that have :box attributes use a
similar construct for the line width argument.  Just to see if maybe the
documentation does not reflect reality in the code?
