evolution-data-server cannot sync ecal against gpilotd

Binary package hint: evolution-data-server

Since natty upgrade, evolution-data-server fails to start from gpilotd during Palm synchronization.

Here is the console output :
>>>

The sync failed, but error is not reported to user (maybe this is a gnome-pilot bug)

Under debian, e-d-s is 2.30.3-2 and the sync works.
