xconsole: Couldn't release PPP unit: Inappropriate ioctl for device

Hi! in xconsole within kde, whenever I stop the internet connection (using kinternet), it says: Dec 28 20:10:47 pinguin pppd[2969]: Couldn't release PPP unit: Inappropriate ioctl for device It seems to be no big problem, I can continue, dial in again etc., but I guess there is never an error without reason. I'm running SuSE 7.2 prof. Updated to kde2.2.2, first with qt 2.3.2, but after an extremely slow konqueror etc. back to the original qt 2.3.0. and then update to qt 2.3.1 using the rpm from trolltec.
