Are you familiar with debugging with Edebug and/or with running Emacs
under GDB?  If so, perhaps you could step into the relevant code and
tell us what happens there with this font, so we could understand the
root cause(s) of this.

Or maybe someone else who can install that font and sees the problem
could do that.
