Error when trying to log into Data Explorer, with OpenID, when already logged on with OpenID
From my user account on the StackExchange Data Explorer (same username as on this site), I try to change my OpenID. After I click this link, I select login with Google, and the next thing I see is the default server error page.
Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
I don't think this some random bug just now, because I have experience this when I've tried to change my OpenID there a couple of times earlier as well.
