I think you have solved the mystery, Scott.

The access time on this executable is 17:19 today, which was the first
time I ran my test for my initial post. (Thankfully I recorded the time
in that post.)  I've tested a few more times since then but the access
time didn't update because (if I recall) the kernel only updates if it
hasn't been accessed in 24 hours.

So the next question is: why is an "suid root" executable needing to be
called?  Can't everything be confined to my user account so that nasty
things can't happen.  I'm not sure exactly what plugin-config does
(apart from configuring plugins :-), but if it is allowed to install
stuff in the /usr/lib64 hierarchy, it would seem (to a security novice
like me) to be a serious security hole.

Anyway, thanks for solving the mystery.
