On 2008-11-07 I had removed packagekit and from then on never saw the error message again even though I had several occasions where an update in synaptic resulted in update packages becoming available. A few days ago I installed packagekit again and today when performing a reload in synaptic I again received the error message. Thus I can confirm it happens only when packagekit is present.
