Text invisible / TypeError: 'RGBA' object is not iterable

[cweiske]

Trying to draw a text on a screenshot with gradia 1.13.0-4 on Debian 13 (with .deb package from debian testing), I get errors:

TypeError: 'RGBA' object is not iterable
Traceback (most recent call last):
  File "/usr/share/gradia/gradia/overlay/drawing_overlay.py", line 769, in _on_draw
    action.draw(cr, self._image_to_widget_coords, scale)
    ~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/share/gradia/gradia/overlay/drawing_actions.py", line 415, in draw
    if self.options.fill_color and any(c > 0 for c in self.options.fill_color):
                                                      ^^^^^^^^^^^^^^^^^^^^^^^

The text is invisible.
The color selection on the left only shows transparent background unless I manually select a color.
