calcOCoords: function() {
      var rotateMatrix = this._calcRotateMatrix(),
        translateMatrix = this._calcTranslateMatrix(),
        startMatrix = multiplyMatrices(translateMatrix, rotateMatrix),
        vpt = this.getViewportTransform(),
        mMatrix = multiplyMatrices(vpt, startMatrix),
        dim = this._calculateCurrentDimensions(),
        options = util.qrDecompose(mMatrix),

        coords[key] = control.positionHandler(dim, finalMatrix, fabricObject);
      });

      return coords;

You should compare with the latest unpublished beta. The problem is still there, but that is the code we want to look at.
I may know how the bug was introduced, i just need time to look for a fix.

Sorry. I don't want to seem intrusive. The code above helped me. Thank you!
