looks like systeminfo tries to use capabilities that are not allowed, so it gets rejected, you can file bug to systeminfo maker and tell him only to use allowed capas.
And you really should not use http://harmattan-dev.nokia.com/ in device since that repo is not meant for N9 (and it easily breaks the depencies).
usually this is badly configured wifi AP which doesnt offer dns server for the phone, so host resolver fails. Or wifi nat behind other wifi nat.
Same things happens sometimes (about 25-50%) in the nokia store. I really don't know is this a bug or not.
