I experienced an issue trying to use edit api on this file: http://commons.wikimedia.org/w/index.php?title=File:Concert.jpg

This happened after I had deleted and then restored the page, see also the log of that here: http://commons.wikimedia.org/w/index.php?title=File:Concert.jpg&action=delete . Whatever I tried, I couldn't make an edit to that page then. Every time I got: {"error":{"code":"pagedeleted","info":"The page has been deleted since you fetched its timestamp"}}

I tried purging the page and my browser, tried waiting a while (2 hours) and switching browsers, the problem would not go away. Perhaps the delete and restore timestamps were too close, confusing editconflict detection, or possibly, the api is looking at the last time of deletion and last time of edit, not realising that an undeletion of the page is an event that can occur after those two times.

I finally solved it by making an edit to the page with the normal interface. After that, everything went like clock work.
