In the post editor when you click on an image that has already been inserted an overlay pops up allowing you to edit the image.
This overlay is displaying things like {#cancel} instead of the word Cancel. All text on this overlay has been changed in a similar way.

I have disabled all plugins and performed an automatic reinstall of WordPress with no avail.
Any ideas?
Downloading TinyMCE from their site and using the language files from the zip fixed the problem.
