If Geeqie is started with no geeqierc.xml file and OSD is selected,
there will be a seg.fault.
Set the OSD font in default options - the font set does not seem to
matter.
options->image_overlay.template_string = nullptr;
options->image_overlay.x = 10;
options->image_overlay.y = -10;
- options->image_overlay.font = nullptr;
+ options->image_overlay.font = g_strdup("Sans 10");
options->image_overlay.text_red = 0;
options->image_overlay.text_green = 0;
options->image_overlay.text_blue = 0;
