Do not add retraces if the bug is a duplicate

Fixed in bzr head.

This bug was fixed in the package apport - 0.103

---------------
apport (0.103) hardy; urgency=low

  * bin/apport-unpack: Print error messages instead of crashing for problems
    like nonexisting file names passed as arguments. (LP: #185273)
  * backends/packaging-apt-dpkg.py, is_distro_package(): Explicitly check site
    for "ppa", so that we do not automatically file bugs for PPA packages.
    This works around Soyuz bug LP #140412 for the time being.
  * apport/report.py: Add standard_title() test cases for Python crashes with
    a custom message, and a custom message with newlines. The latter
    reproduces LP #190947.
  * apport/report.py, standard_title(): Do not rely on a fixed position of the
    topmost function; use iteration and regular expression matching instead.
    (LP: #190947)
  * apport/ui.py, parse_argv(): Specify that --pid/-P argument must be an
    integer, to avoid exceptions when it's not. (LP: #193494)
  * apport/report.py: Use uname -srm, not -a, to hide the hostname. (part of
    LP #192786); also use os.uname() instead of calling the system program.
  * problem_report.py(): Make write() work for reports with CompressedValues.
    Add test case.
  * apport/ui.py: Add test case test_run_crash_anonymity() which asserts that
    the crash dump does not contain strings which can identify the user, such
    as the user name, login name, host name, and current directory.
  * apport/report.py: Add method anonymize() which replaces user specific
    strings with generic ones.
  * apport/ui.py, thread_collect_info(): Call anonymize() on the report.
    (LP: #192786)
  * bin/apport-retrace: Only update a bug report with new attachments if it is
    not a duplicate. (LP: #172792)
  * bin/apport-retrace: Print out proper error message instead of an exception
    if trying to do write operations to the bug tracker without specifying
    a cookie file. (LP: #146423)
