Subject: 30.0.92; doc-view: Saving an epub raises error in
 doc-view--revert-buffer
Date: Sun, 12 Jan 2025 15:29:53 +0100

I was editing an epub file.  When I save, I get an error from
doc-view--revert-buffer.  I have reproduced the problem with "emacs -Q".

Steps:

* Open an epub file.  (I can make a minimal example file, if that
  helps.)
* Switch to archive mode with C-c C-c.  (Epubs are zip files.)
* Open and edit one of the files in the zip.
* Save the file (C-x C-s).
* The mini-buffer shows "Wrong type argument: stringp, nil".  Running
  with debug-on-error gives the backtrace below.
* The Zip-File was actually saved, but the archive buffer is left in a
  raw-bytes mode and the modified file is still marked modified.
