Right, it shouldn't crash.

FWIW, The problem is (org-footnote-get-next-reference ...)  sees the
following text while looking for next reference.


\begin{verbatim}
lst = [-1, -2, 2, -3, -4]

for x in lst[:]:
    if x < 0:
        lst.remove(x)

        print(lst) # [2] <- does not work!
\end{verbatim}

AFAICS the above text has no text decorations as well.

Naturally org-footnote-get-next-reference is misled into believing that
it is in the "allowed" territory.
