Cardapio Problems

hey all im using openSUSE 11.3 GNOME and I tried installing cardapio using bzr, with the instructions from the official launchpad page.
It shows up in the ‘add to panel’ button but when i try to add it to the panel it gives me this error message:

The panel encountered a problem
while loading
“OAFIID:GNOME_Cardapio”.
Do you want to delete the applet from your configuration?

Don’t Delete
Delete

I tried logging in and rebooting but i get the same message.
Any suggestions? thanks!
