Encountered on: https://en.wikipedia.org/wiki/Westplex?veaction=edit Firefox 21.0 on openSuse 12.3 When opening the "Media settings" overlay by clicking the icon on the image, the title shows <visualeditor-dialog-media-content-section> instead of what I assume should be the actual system message.
Fixed by Gerrit change #69497 which we will try to get pushed today.
