Er, what bonobo_activation_register thing? I don't really know anything
about Bonobo, I just copied the applet examples, and I didn't see any
bonobo_activation_register anywhere :-/.

If I run it manually, the same thing seems to happen.

I don't really know what else I can do now except show the relevant bits
of code etc in the hope that someone can spot my mistake.

This is the main bit of code I'm using, which I've hacked with macros a
bit to try to debug it:

#undef panel_applet_factory_main

static int my_factory_main(const gchar *iid, GType applet_type,
	PanelAppletFactoryCallback callback, gpointer data)
{
    int result;

    panapp2_set_log_handler();
    g_log(0, G_LOG_LEVEL_DEBUG, "About to call panel_applet_factory_main:\n"
	    "  iid: %s\n  applet_type: 0x%lx\n  callback: %p\n  data: %p",
	    iid, applet_type, callback, data);
    result = panel_applet_factory_main(iid, applet_type, callback, data);
    g_log(0, G_LOG_LEVEL_DEBUG, "Result of panel_applet_factory_main = %d",
	    result);
    return result;
}

#undef gnome_program_init

static GnomeProgram *
my_program_init(const char *app_id, const char *app_version,
		    const GnomeModuleInfo *module_info,
		    int argc, char **argv,
		    const char *first_property_name, ...)
{
    GnomeProgram *result;
    va_list ap;

    panapp2_set_log_handler();
    g_log(0, G_LOG_LEVEL_DEBUG, "About to call gnome_program_init:\n"
	    "  app_id: %s\n  app_version: %s\n  first_property_name: %s",
	    app_id, app_version, first_property_name);
    va_start(ap, first_property_name);
    result = gnome_program_init(app_id, app_version, module_info, argc, argv,
	    first_property_name, ap);
    va_end(ap);
    return result;
}

#define panel_applet_factory_main my_factory_main
#define gnome_program_init my_program_init

PANEL_APPLET_BONOBO_FACTORY("OAFIID:TgaugeApplet_Factory", PANEL_TYPE_APPLET,
	"Tgauge", "0", panapp2_fill, NULL)

/* End */


The "About to call" messages both get printed, but I've also got a
message at the start of my panapp2_fill function, and that never gets
run.

I've installed the binary as /usr/lib/gome-applets/tgauge_applet2
because that's where the other applets are installed, and similarly, my
.server file is /usr/lib/bonobo/servers/GNOME_TgaugeApplet.server. Am I
supposed to do anything besides copy it there? The Makefile.am's for the
existing applets didn't seem to do anything special, and an entry does
appear in the panel menu.

Here are the contents of GNOME_TgaugeApplet.server:
