It seems that some of the JS in deployment uses $ now instead of $j and I think that this is related. I get the error
plugins.combined.min.js:126
TypeError: Result of expression '$j.wikiEditor' [undefined] is not an object.

The jQuery 1.4 migration was completed this morning, some 20 hours after your report. Prior to that, the last change to deployed JS was on October 4, and the last change that seems like it could be remotely related was on September 13.

That's strange, where are you getting that exactly?
I got it yesterday on English Wikipedia, several minutes before the opening of the bug. The problem was at all dialogs and on multiple pages. It seems gone now.
Could be caused by site JS maybe, or maybe it's just a fluke (JS file failed to load or something). Closing as WORKSFORME unless and until someone can reproduce.
