Bugs in Thumbnails creation - v3.1.1 and also v3.1.2

[shawn_a]

Works fine for me.

I do notice that thumbnails don't show up when uploading hem though in the file list, if you change to image it says
Uncaught ReferenceError: attachFilterChangeEvent is not defined
you have to reload.

Also I don't think thumbnails are created until you click the image to preview it.

But that is working for me, I get an auto sized 200px thumbnail.
