ED's convoluted Python/NTLK stuff for diagnostics just doesn't work on the new Jenkins server, and in any case it seems, as we look at it, that it could perfectly well have been done in XSLT, so SK and I have made a start on figuring out how it works and converting it. It'll take a while, but lesson learned -- don't let people use stuff just because they like it, keep the range of tech limited for any given project.
