Louis,
a hunch, which might work.
It seems that, if you try to set the length in your preamble,
`\beamer@frametextheight` is not yet defined.
So, you might try the hook `\AtBeginDocument` to see if the
definition comes at
a better timing.
#+LATEX_HEADER:
\newlength\mytextheight\AtBeginDocument{\makeatletter\setlength\mytextheight{\beamer@frametextheight}\makeatother}
As I said, it's a hunch, for I haven't tested. But I think it
may be it.
Why not put the entire thing inside \AtBeginDocument?
To the OP: \paperheight does seem to be available in Beamer.
Couldn't you use that?
