I attempted to make this HTTP POST request to api.php on testwiki: action=stabilize&title=Gold&token=<VALID EDIT TOKEN>&protectlevel=autoconfirmed&expiry=1%20month&reason=vandalism&format=xml An HTTP 500 Internal Server Error, with no debug information, was returned. Apparently the same occurs on enwiki. As far as I can see, the query is valid. Therefore the action=stabilize API is broken on these wikis, which in my view is a serious bug.
