Yes:
0. HOME=$(mktemp -d) emacs -Q &
1. (progn
(setq url-automatic-caching t)
(dotimes (_ 2)
(with-temp-buffer
(url-insert-file-contents "https://debbugs.gnu.org/26063"))))
2. C-x C-e
Debugger entered--Lisp error: (file-error "https://debbugs.gnu.org/26063" "Not
modified")
signal(file-error ("https://debbugs.gnu.org/26063" "Not modified"))
url-http--insert-file-helper(#<killed buffer> "https://debbugs.gnu.org/26063"
nil)
url-insert-file-contents("https://debbugs.gnu.org/26063")
(progn (url-insert-file-contents "https://debbugs.gnu.org/26063"))
...
This happens on both emacs-26 and master.
Thanks,
