And I got a backtrace.

The code is:

(defun gnus-html-image-fetched (status buffer image)
  "Callback function called when image has been fetched."
  (unless (plist-get status :error)
[...]
    )
  (kill-buffer (current-buffer)))

So when we get an :error, sometimes the http buffer doesn't exist?
That's just weird.
