Binary package hint: screenlets

Just upgraded to Ubuntu 10.10 beta from 10.04 LTS. Many bugs this is one of them.
Expected: the screenlet should work with the sysmonitor applet run on ubuntu logging in.
what happens: The screenlet is working, but the applet sometimes times doesn't. Restarting the applet seems to make it work again.
How to reproduce: I don't really know how!
