Title:
  package_hook will gzip a file a second time

Status in apport package in Ubuntu:
  Incomplete

Bug description:
  ubuntu-release-upgrade contains code (DistUpgradeApport.py) that calls
  /usr/share/apport/package_hook with the argument -l for adding log
  files from /var/log/dist-upgrade to bug reports.  One of the log files
  added is apt-clone_system_state.tar.gz which is already a gzip'ed
  file.  This is then added to the crash file as -
  VarLogDistupgradeAptclonesystemstatetargz: base64 - which then gets
  gzip'ed again during the upload process.  Bug 1249583 contains an
  example of this attachment.

  One can recreate this by running the following code:

  #!/usr/bin/python

  import subprocess

  p = subprocess.Popen(["/usr/share/apport/package_hook", "-p", "slrn",
      "--tags", "dist-upgrade", "-l",
      "/var/log/dist-upgrade/apt-clone_system_state.tar.gz"],
      stdin=subprocess.PIPE)
  p.stdin.write("ErrorMessage: Test Failure")
  p.stdin.close()

  And inspecting the resulting crash file in /var/crash.  It'd be
  helpful if these were not gzip'ed a second time.  For what it i worth,
  some time ago I dealt with the same issue in the update-manager
  package hook by using attach_file instead of
  attach_root_command_outputs.
