Yeah, my guess is that the error is in org-odt-format-label. It used to
be that an inline formula would not have a label. But now it does. So
label is non-nil. The attached patch seems to fix it, but
org-odt-format-label is pretty fragile in its assumptions...
I also pushed a fix to org.el that may be related if you e.g. use
latexmlmath.
For the record, it can be reproduced with the following example from
emacs -q.
—Rasmus
* set up :noexport:
#+BEGIN_SRC emacs-lisp
(require 'ox-odt)
(setq org-latex-to-mathml-convert-command
"latexmlmath \"%i\" --presentationmathml=%o")
#+END_SRC
* test
see \(x\)

Don't panic!!!
