Ok. Got a "weird" issue with OpenSuSE 13.1: doesn't matter which desktop I use (lxde or xfce4 for example), when i click on menu>settings>install/remove software nothing happens. however, when i run the command: xdg-su -c "/sbin/yast2 --gtk" and run software management that way, again nothing happens (neither when i click on menu>settings>yast) HOWEVER: when i run xdg-su -c "/sbin/yast2 --qt" I am able and successfully able to run software management. Can anyone explain to me why and how to fix this so that Install/Remove programs works "correctly" from ANY desktop environment?

output of xdg-su -c "/sbin/yast2 --gtk" command:
