[Bug 399709] Re: add-apt-repository creates read-only sources.list

[Jarno Suni]

** Description changed:

  by default `sudo add-apt-repository ppa:username` creates a file
  /etc/apt/sources.list.d/username-ppa-karmic.list with the default umask-
  based permissions which in my case on karmic left with a file readable
- only be root
+ only by root
  
  this causes all non-superuser run apps that legitimately probe the
  contents of /etc/apt/sources.list to fail
  
  e.g.,
  
  $ apport-cli -f -p python-software-properties
