HTTP 500 error in oauth settings page?

A week ago the oath settings page (Log into my account > settings > oauth settings) was fine, but as of yesterday is returning a 500 error (text below). I had another user test, and tried from both Mac and tablet and all get the same. Is anyone seeing this? Did something change?
thx

Error:

Application error
The OpenStreetMap server encountered an unexpected condition that prevented it from fulfilling the request (HTTP 500)

Feel free to contact the OpenStreetMap community if your problem persists. Make a note of the exact URL / post data of your request.

This may be a problem in our Ruby On Rails code. 500 occurs with exceptions thrown outside of an action (like in Dispatcher setups or broken Ruby code)

I mentioned this problem on IRC in #osm-dev and got the reply “been fixed already”, so I guess you might want to give it another go if you haven’t already?
