I have no way to determine that more that he does (and did).

Sorry, it's been 3 years and I don't have anything more to offer
about this.  If you don't want to make the code less brittle and
fix the case where the value is nil, so be it.

Personally, I don't use tmm anyway.  It's possible that I
happened to notice this problem when looking at the code.
Or perhaps I ran into it while experimenting with the code.
I really don't know.
