==== Impact ====
Unable to use the reply tool or the new topic tool. It works when being logged out, so I’m not sure how many people are affected by this (but those who do, are quite severely).
==== Notes ====
* Tried to reply my 07:23 comment and to start a new topic on that page. The stack trace is from the reply attempt. (The error message is the same when trying to start a new topic; I didn’t compare the stack traces.)
* Happened logged-in, I was unable to reproduce it logged-out with the very same URL. Preferences that might be interesting (that I know are different from the defaults):
** UI language: Hungarian (`hu`)
** Skin: Timeless
** All DiscussionTools preferences are on, except for automatic topic subscriptions and source mode toolbar. Adding `&dtenable=1` to the URL while logged out didn’t make the issue reproducible.
* The URL contains `&debug=true`, but that’s only to get an easier-to-understand stack trace, it’s broken without `&debug=true` as well.
