Can you explain how this problem is avoided with gksu, or gksudo? So far
as I can see using one of these causes the application to run with UID
of 0, i.e., root. The app has no knowledge of how it was invoked, so any
files is creates will be owned by root.

Your explanation applies to running any app, not just graphical ones.

http://www.psychocats.net/ubuntu/graphicalsudo

That page says that "sudo nano /etc/apt/sources.list" is a good idea.
It isn't, and for the same reason graphical apps shouldn't be run
through sudo -- nano will create/edit extra files in your home
directory. In fact, there's a command called "sudoedit" which solves the
problem.

Aha!

Here I was thinking that there was a bug in nano that made the
~/.nano_history file belong to root, and all along it was simply the wrong
command for the job!

Do you happen to know under what circumstances the permissions change?
The above does not always occur, which is one reason that I was confused...

Thanks - this helps to solve one of the little problems that I have been
wrestling with in my live CD project.
