kdialog - Session bus not found

[Brad Hubbard]

Is this expected?

It's new in f22 AFAICT.

$ kdialog --title "Test" --passivepopup "Test" 2
kdialog(10183)/kdeui (kdelibs): Session bus not found 
To circumvent this problem try the following command (with Linux and bash) 
export $(dbus-launch) 
KCrash: Application 'kdialog' crashing...

I understand that the following works just fine but I'm just wondering if anyone
knows if this is the way it's meant to be now and what the reasoning is?

$ export $(dbus-launch) && kdialog --title "Test" --passivepopup "Test" 2

Thanks,
Brad
