[PLUG] kdesu question

When I first upgraded from Leap 42.3 to Leap 15.0, kdesu ran just fine. 
But after adding some software archives, then updating those, the 
problem appeared.

I built several of the desktops, then rebuild plasma (for kde) and kdesu 
worked okay again. But then I did a "zypper dup" command, and after that 
kdesu failed again.

 From the command line: %kdesu yast2
I get the pop-up box, enter the password and everything hangs.
In the command line terminal, the word: kdesu_stub appears on the next 
line down, and hangs

Yes, but I was simply using the prebuilt yast2 icon which should work 
automatically.
I can type in the command line
%su
%yast2
on 2 separate lines, and everything is fine.

I guess I could hack the yast2 icon on the task bar and fix this 
manually, until the next upgrade, then start all over again.

Thank you for your questions
