One minor nit: I think the SRU version should be 2.4.1-2ubuntu4.1 rather than 2.4.1-2ubuntu5, but in this case I believe it's okay given that based on https://launchpad.net/ubuntu/+source/nut/+changelog, it doesn't appear that there was a 2.4.1-2ubuntu5 in the karmic dev cycle.

Otherwise, fix looks good.
