PHOTOSHOP: "could not transform the path because the selected portion of the path does not enclose any pixels" bug

Whenever I press ctrl + T to transform a layer, it gives the "could not transform the path because the selected portion of the path does not enclose any pixels" statement and doesn't do the action. I don't understand if this is a bug or if there is some solution to this silly problem.

I've restarted Photoshop and tried it on several different layers...
