This problem seems to have returned. Has anybody else noticed it?
Yes, me too. An odd "<Filename>kde-" line somehow reappeared ^^^ in "$USER_DIR/.config/menus/applications-tdemenuedit.menu". That was test #9. Solution is as it were: delete the lines with "kde-"-something in that file.
After upgrading packages about a week ago, everything seemed to run fine until I started having very strange network issues. I rebooted, and got this same message as I remember from some old threads.
Every other problem on your system seems to very mysteriously be connected with very strange network behaviour… Maybe let a powerful shaman drive these daemons out of your box with some kind of ritual… ;-)
Kind regards, Stefan
