Title:
  aborts rather than printing warning when configuration file is
  inaccessible

Status in Bazaar Version Control System:
  In Progress
Status in “bzr” package in Ubuntu:
  Triaged

Bug description:
  when opening a configuration file raises PermissionDenied, bzr prints
  it (with a backtrace) and aborts.

  Instead, it should just ignore the configuration file, print a warning
  and continue.

  This is causing also causing problems when running the tests under
  fakeroot. When we create a safety net, the users' configuration file
  is read. If this configuration file is e.g. in /root the tests blow up
  spectacularly.
