BGRAImageManipulation access violation was created by universe

Hello, I noticed an access violation on click (without making selection a window) for BGRAImageManipulation and the code exception is raised from line 2626 in BGRAImageManipulation.pas

procedure TBGRAImageManipulation.MouseUp(Button: TMouseButton;
  Shift: TShiftState; X, Y: integer); 
.....
.....
      //------> Access violation on single click
      if not assigned(rSelectedCropArea) then exit;//this fixes the issue
      if (rSelectedCropArea.Area.Left > rSelectedCropArea.Area.Right) then
      begin
        // Swap left and right coordinates
        temp := rSelectedCropArea.Area.Left;
        rSelectedCropArea.Area.Left := rSelectedCropArea.Area.Right;
        rSelectedCropArea.Area.Right := temp;
      end; 
....
....

so I just added the line

if not assigned(rSelectedCropArea) then exit;

It fixes the issue (file attached)
