Title:
  apport breaks if /etc/apt/sources.list doesn't exist

Status in apport package in Ubuntu:
  Incomplete

Bug description:
  I split all my repos nicely in /etc/apt/sources.list.d/ files. apport
  breaks in that case.

  I assume this could easily be fixed with os.path.exists().

  The workaround of creating an empty /etc/apt/sources.list works fine, but that's incompatible with my OCD.
  That's obviously what I did to be able to file this bug. Here's the traceback without:
