tdenetworkmanger again: wired icon is not working

Hi I am running Trinity, having installed it from the latest CD live, using Ubuntu 14.04. On monday I set my wired net with the tdenetworkmanager only. Everything worked fine, the connection was set manually, the connected icon for wired showed up. Then yesterday, I connected to a wirless net, using tdenetworkmanager, again everything fine. Today I deactivated the wireless card and tried to connect again to the wired net. It did not work. I found out that the resolv.conf file, which is a link from /run/resolv/resolv.conf --> /etc/resolv.conf was empty. So I manually set a new connection, but the resolv.conf file was not changed, I replaced the resolv.conf file by the correct file and then the connection worked, however the icon, still shows wired connection *not* connected. This is annoying. Does anybody using the same distribution have this problem and knows a solution? Thanks Uwe Brauer
