Did some more digging, and it's none of the above. Turns out it's a bug 
in tigervnc server that I'm using to get access to the backend machine 
to build on. If I ssh to it, the problem goes away. I suspect tigervnc 
is not properly setting up the user and ccache is calling something like 
mktemp() and that is getting to the user that kicked off the tigervnc 
session (root).

Not a MythTV bug.
