puplet says I have 47 updates available. I choose to install the updates, and after entering the root password an error dialog appears. I'll attach the stack trace. I suspect the problem is that pup tries to print something and there is no place to print it. Running pup from the command line works fine.

I don't get this at all... what yum plugins do you have installed and what are the versions of yum and pirut installed?
I don't recall what versions of yum and pirut I had ... I've updated a few times since then. I think I ran puplet in a terminal which I later closed. But even that I don't remember for sure, sorry. FWIW puplet as run during the normal login process seems to work fine.
I can't reproduce this trying here, so closing :/
