You also need to start a dbus session for the new user.

Comment 2 deviatov 2016-05-25 14:19:49 UTC 
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?)
