I should have added that the problem is in org-create-formula-image-with-dvipng,
in the code that tries to set the background around line 17616:

,----
|     ...
|     (if (eq bg 'default) (setq bg (org-dvipng-color :background))
|       (setq bg (org-dvipng-color-format bg)))
|     ...
`----

bg is "Transparent" and org-dvipng-color-format barfs on that,
since it cannot find it in the color "database".
