My rhn_update task bar applet is now out-of-sync with up2date. (Core 2/test2-3) The applet thinks I need to update an RPM, and so its flashing red. Cliking on it says indeed, there is a new RPM to fetch, but... When I start up2date, it says my system is completel;y up to date. How can I get the two applications back in sync?
