Duplicate sources.list entry (apt-get)

It’s been bugging me for some time now. Whenever I do an apt-get update I get a warning:

# apt-get update

W: You may want to run apt-get update to correct these problems

Obviously /etc/apt/sources.list doesn’t have any duplicate entries for the repository, so where does the warning stem from? Checking in /etc/apt/sources.list.d reveals a file called ksplice.list. The information in this file is the same as my entry in /etc/apt/sources.list so one entry has to be removed. I choose to move the file /etc/apt/sources.list.d/ksplice.list out of the way. I prefer keeping my sources in /etc/apt/sources.list as this makes it easier to maintain between both upgrades and other machines.
