TeX-complete-list contains an entry

   (LaTeX--after-math-macro-prefix-p 1
                                   (lambda nil
                                     (append
                                      (mapcar #'cadr LaTeX-math-list)
                                      (mapcar #'cadr LaTeX-math-default)))
                                   (if TeX-insert-braces "{}"))

(see latex.el:8074) and LaTeX-math-default contains an entry where the
cadr is the symbol LaTeX-math-cal.  I guess, there should be a
(seq-filter #'stringp ...)  around the (append ...).

Bye,
Tassilo
