Nautilius error starting SJDE solaris 10

I get this error when SJDE is starting just after the login screen:

"Nautilius cant be used now, due to an unexpected error from Bonobo when attemping to register the file manager view server. There was a probem registering the panel with the bonobo-activation server. The error code is: 3. The panel will now exit."

The screen is black, and the only way to exit is killing the xserver process from the process management window.

What could be the solution...?

thanks a lot
