Hi all!

I just installed mark-my-words from the default repos. 
On launch, however, all I get is the following:

  (mark-my-words:20778): Gtk-CRITICAL **: gtk_image_set_from_icon_name:
assertion 'GTK_IS_IMAGE (image)' failed
  (mark-my-words:20778): Gtk-CRITICAL **: gtk_tool_button_set_icon_name:
assertion 'GTK_IS_TOOL_BUTTON (button)' failed
  (mark-my-words:20778): Gtk-CRITICAL **: gtk_image_set_from_icon_name:
assertion 'GTK_IS_IMAGE (image)' failed
  (mark-my-words:20778): Gtk-CRITICAL **: gtk_tool_button_set_icon_name:
assertion 'GTK_IS_TOOL_BUTTON (button)' failed

And nothing more.
No window opens, nothing else happens.
I am on Leap 15.1 with the Gnome 3.26.2 DE.

Maybe the maintainer should have a look at it.

Cheers!
