How did you get back to the page where you added
"[[meta-wiki]]"?
If you used the Back button in your browser, you need to refresh the
page after creating the actual "meta-wiki" page.

It doesn't seem to be a caching problem. I used Firefox's Live HTTP
headers plugin to make sure the page was regenerated. Even when the page
is regenerated it still has action=edit added to the link. There seems to
be a problem with logic that determines whether or not to enable editing
for a page.
