I think I got that right:

#define OPTSDBUS_NAME "net.sf.roxterm.Options"
#define OPTSDBUS_OBJECT_PATH "/net/sf/roxterm/Options"
#define OPTSDBUS_INTERFACE "net.sf.roxterm.Options"

I got a private message from someone who thought that signals couldn't
actually have arguments. Is that right? That would explain it. It would
mean I couldn't easily use signals to broadcast my config changes

Sorry, I didn't get how the receiving of messages was integrated into
the main loop if GProxy signals weren't working. But looking at
ROX-Session as an example I can now see that dbus has its own system of
callbacks (ROX-Session uses dbus_connection_register_object_path; I'd
probably need to use something slightly different for signal messages).
