Not sure how to correct this one, that extra line is a hold over from an experiment i tried to perform when i was using Mint 13 Maya, i tried to import a repository in order to get a splash screen and yes using Ubuntu Tweak, somehow that line remained even though I'm using Mint 9 Isadora, now that line doesn't exist in Software Resources but it does in Ubuntu Tweak, and i would gladly delete it but each time i try it keeps coming back, and that after saving the changes more than a few times.. All of this happened over Mint 13 and my attempt to get one "splash screen".. ah well, back to the drawing board this may take some time..
Thanks for the help..
