It turned out that the culprit was the following 


 (add-hook 'gnus-select-article-hook 'my-org-store-link-simple)
 (defun my-org-store-link-simple ()
   (interactive)
     (call-interactively 'org-store-link))

No idea why I put this in, and no idea why this interfere with the wide
and very wide reply commands.

I leave it to the maintainer to close the bug.
