Perhaps you could use git-bisect to find the ID of the offending commit?

Also a reproduction recipe would be useful.  Does this bug only occur if
`org-export-as-odt-and-open' is called, or can it be reproduced by
simply calling `org-preview-latex-fragment' or
`org-create-formula-image'.

Note: my patch (referenced above) did not touch the
`org-create-formula-image-with-dvipng' function which appears in your
backtrace (below), so I doubt my commit is the culprit.

Best,
