The Text Editor gadget doesn't display the text unless there is an image

The text editor gadget doesn't display the text typed in the rich text editor unless you upload an image in the gadget. Plus the image size is automatically adapted to take the whole width of the gadget (which in my case makes my tiny little 1 pixel picture very large and useless).
The title is correctly displayed.

Plus, the default name of the gadget is "Edteur de texte" instead of "Editeur de texte".
