How to add panel applets in GNOME-2?

[Toralf Lund <toralf procaptura com>]

I'm trying to port a custom applet to GNOME-2. I've got to the state where 
I have build installed the actual executable along with the bonobo 
.server, but I'm not able to load the applet. No entry appears on the "Add 
to panel"-menu, and if I execute the applet "by hand", it will exit 
immediately without giving any error messages. Exit code is 1.

Questions:
1. What exactly is needed to add entries to applets menu? Is the 
information in /usr/lib/bonobo enough, or do I need different config files 
etc.?
2. How do I debug my setup? Can I get bonobo/gnome-panel to tell me what 
is wrong with the applet or "server" config?

I'm using GNOME 2.2 on Red Hat 9.
