apport-retrace does not modify the original report as expected with no option specified

[KDEUSER56]

Current behavior: When calling apport-retract and specifying a .crash file, apport-retrace tells me the following:
Usage: apport-retrace [options] <apport problem report | crash ID>

apport-retrace: error: you either need to do a local operation (-s, -g, -o) or supply an authentication file (--auth); see --help for a short help

Expected behavior: apport-retrace should modify the specified file, as indicated by the man page.

This demonstration was recorded on today's utopic iso.

I have installations of the last 3 ubuntu releases (saucy, trusty, utopic) and this bug affects all of them (though trusty is as of 14.04.1 and hasn't been upgraded since then).

Fixed in trunk r2845.

This bug was fixed in the package apport - 2.14.7-0ubuntu1

---------------
apport (2.14.7-0ubuntu1) utopic; urgency=medium

  * New upstream release:
    - Fix interpretation of core dump ulimits: they are in bytes, not KiB.
      (LP: #1346497)
    - apport-retrace: Don't require specifying an operation; default to
      updating the given .crash file. (LP: #1361242)
    - Write report even on UnreportableReasons, so that whoopsie can still
      upload them. (LP: #1360417)
    - apt/dpkg install_packages(): Write a "packages.txt" into sandbox root
      directory to keep track of installed packages and their versions.
      Prerequisite for LP #1352591.
    - apt/dpkg install_packages(): Avoid re-downloading/installing packages
      which are already installed into a permanent sandbox. Prerequisite for
      LP #1352591.
    - sandboxutils.py, make_sandbox(): Drop check for already existing files
      when dynamically resolving libraries and ExecutablePaths; with that,
      these packages would never get updated in a permanent sandbox. The new
      version tracking from above now takes care of that. (LP: #1352591)
    - Fix report.test_add_proc_info test to stop assuming that pid 1 is named
      "init", as one can specify a different one on the kernel command line.
    - report.py, add_gdb_info(): Check for truncated core dumps, and set
      UnreportableReason and raise an IOError on them. Handle this in
      apport-retrace and whoopsie-upload-all to fail properly instead of
      silently producing broken Stacktraces. (LP: #1354571)
