I think insert-file-contents should behave same regardless gpg file or not.

$ echo -n test > file
$ gpg -c file

elisp> (insert-file-contents "file" nil 0 4) ;; no error
elisp> (insert-file-contents "file" nil 0 5) ;; no error
elisp> (insert-file-contents "file.gpg" nil 0 4) ;; no error
elisp> (insert-file-contents "file.gpg" nil 0 5) ;; error

I had no chance to fix that on my side.

Best,
