Comment 1 RHEL Product and Program Management 2009-03-18 10:01:58 EDT
This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.
Comment 2 John Matthews 2009-03-18 13:17:30 EDT
This message shows up when the applet cache file doesn't exist.  The error message is harmless.  It's been fixed in this commit #182619

To test this:
1) rm ~/.rhn-applet.cache
2) rhn-applet-tui

The old RPM shows the "Exception" message
New RPM adds a check if the cache exists.

Committed revision 182619.
