When I start IDLE I get this:

That's fine (if slightly confusing regarding the version numbers), but
if I click Options->Configure I get this error output:

I tried changing xrange to range, but that doesn't work:

Amaury Forgeot d'Arc says he's fixed this in change 59456 (but I don't
know how---or if---I can change its status).

Fixed in r59456
