You also need to start a dbus session for the new user. *** This bug has been marked as a duplicate of bug 270442 ***
I've tried to start dbus as follows: first, I typed (as the normal user) kdesu -u rostislav_www -n -c konsole & then, in the new terminal: dbus-launch xdg-mime query default application/pdf The same crash (with the same backtrace). Am I doing something wrong? (Maybe, I should start dbus somewhat differently?)
