-------------------------------------------------


Expected results:
Evolution works as usual.

Additional info:

I upgraded all Evolution packages to updates-testing, then observed the failure.  I downgraded all Evo packages to those in updates, but accidentally failed to downgrade evolution-data-server.  Still observed the problem.  I downgraded evolution-data-server to the version in updates and the problem disappeared.  (Hence the choice to file under this component.)  The current version in updates is evolution-data-server-2.24.2-1.fc10.
