Comment 13 for bug 335239

A couple of things come to mind, First under "Settings", then "Filters", and "Search Filters", do you have everything selected? Also have you run

    apt-get update

and

    apt-get upgrade

 to the newest packages? May be stupid questions, but I would like to rule out the simple solutions before diving deeper into this. If you have updates that are installed (even if they are not synaptic), please confirm this behaviour still exists afterwards
