The commit `d02ad1f207e1579aff8f36f740a065d71472c182` introduced the
use of `replace-buffer-contents` when available. This function was
introduced in emacs 26.1, hence the version tests.

There must be an issue with the `replace-buffer-contents` calls. Can
you call `trace-function` on `replace-buffer-contents` and trigger the
behaviour again to see what it returns ?

You said it also happens with `emacs -q`, right ? I'll try to see if I
can reproduce with emacs 26.1 tomorrow.
