Heya!

I'm having issues creating a regular Hyperbole button with {C-h h i c}
and Info-index.

I wanted to link to a specific info page, however, after setting a label
and attempting to link to Info-index, I get the error:

Debugger entered--Lisp error: (error "Cannot clone a file-visiting buffer")
  error("Cannot clone a file-visiting buffer")
  clone-buffer()

  hui:menu-act(hyperbole nil nil nil)
  hyperbole(nil nil nil nil)
  funcall-interactively(hyperbole nil nil nil nil)
  command-execute(hyperbole)

Version is 20240401.1927.

I'm also noticing that regular info is broken as well:

{C-h h i c eat<RET>info<RET>}

Creates the following:

<[eat]> - <nil nil nil>

Thanks in advance for any help.

Sincerely,
Marc
