I am having this problem, but on only one of my computers. I'm running Arch
Linux on both machines, both have the same version of the qtbase, and the same
version of polkit-kde-agent. They are basically two identical installations.
Same package set, Same versions, Even the same theme and wallpaper. Two almost
identical installations. The only real difference between these machines is,
one is an Intel Laptop, and the other is an AMD Gaming PC. The AMD system has
no problem. But the Intel system fails every single time. I can manually start
/usr/lib/polkit-kde-authentication-agent-1 from a terminal. The moment i use
it, it will authenticate once, and then crash.  The output it exactly as others
have posted (See below).  Why it works on my AMD system, and Not my Intel
system, is a bit strange. I would be curious how many people reporting this bug
are on Intel systems vs AMD. That could be valuable information.
