[tde-users] message bus - connection refused - WTF?

This issue just started, seemingly out of the blue. My system has been running just fine, and I haven't made any changes or installed anything new or upgraded in a long time. The first signs I had were earlier this evening, when suddenly one of my external hard drives was not recognized. When I tried mounting and unmounting, everything seemed very slow; still couldn't get it to recognize that external hard drive. Finally I unmounted everything, then tried just that hard drive, and it mounted normally. When I tried to open it, however, Konqueror started acting really weird, and a window opened but nothing was displayed. At last I decided to reinstall my system, but after booting up again, nothing has changed in this behavior. I did finally get a message window (not in TDE style, but rather in XFCE or Gnome or whatever) saying something like "message bus could not connect, connection refused - but why all of a sudden? Everything has been running great. It occurs to me that somebody on the mailing list mentioned that Konqueror was acting a little weird, and I wondered if this could be related. I am running Devuan Chimaera (= Debian Bullseye) and currently using the TDE stable repositories. Any help would be appreciated. Bill
