Have you tried using grunt-contrib-uglify 0.1.1rc6?

using 0.1.0:
~/Sites/work/.../trunk ⮀ grunt
Running "uglify:dist" (uglify) task

~/Sites/work/.../trunk ⮀npm install grunt-contrib-uglify@0.1.1rc6

~/Sites/work/.../trunk ⮀ grunt

Thanks this is a good solve. Someone should put this on the README right away on the home page as this issue will be around for a little while I'm sure
