Dear Stardiviner,

I used the "scimax" configuration. Scimax's maintainer, John Kitchin,
helped me out to find the root cause of the problem, i.e. the following
addition to " python-font-lock-keywords":

(setq python-font-lock-keywords
      (append python-font-lock-keywords
     '(;; this is the full string.
;; group 1 is the quote type and a closing quote is matched
;; group 2 is the string part
(
;; "f\\(['\"]\\{1,3\\}\\)\\([^\\1]+?\\)\\1"
"f\\(['\"]\\{1,3\\}\\)\\(.+?\\)\\1"
;; these are the {keywords}
("{[^}]*?}"
 ;; Pre-match form
 (progn (goto-char (match-beginning 0)) (match-end 0))
 ;; Post-match form
 (goto-char (match-end 0))
 ;; face for this match
 (0 font-lock-variable-name-face t))))))

Commenting out this code snippet, the fontfying / HTML-export problem goes
away.

Cheers,
sebastian
