I think that explains it: split-string takes one mandatory and two
optional arguments (separator regexp and an omit-nulls boolean) in
emacs-22/23; but only *one* optional argument in emacs-21 (the separator
arg). The org latex-exporting code calls it with two optional arguments
and that makes the emacs-21 implementation of split-string blow up.

I just did an experiment: in my emacs-23, I called split-string
with one mandatory and *three* more arguments:

(split-string "foo
bar
baz" "\n" t t)

and I got output which looks very similar to what you are getting.

So I think it's an incompatibility with emacs-21. Try the following
patch for now and let us know whether it resolves your problem:
