There is also not a check to see whether or not the path in
InterpreterPath or ExecutablePath is current. From sandboxutils.py:

   # package hooks might reassign Package:, check that we have the originally
    # crashing binary
    for path in ('InterpreterPath', 'ExecutablePath'):
        if path in report and not os.path.exists(sandbox_dir + report[path]):

So we only check for the existence not whether or not it is recent.
Subsequently, a retrace with a old executable can fail like so.

Bug description:
  I was trying to retrace a crash that failed with the retracers in the
  Ubuntu Error Tracker.  I'm using gdb-multiarch from the following PPA
  (https://launchpad.net/~daisy-pluckers/+archive/ubuntu/daisy-seeds)
  and apport from bzr revision number 2818. The command follows:

  PYTHONPATH=$PYTHONPATH:/srv/daisy.staging.ubuntu.com/prod
  uction/apport python /srv/daisy.staging.ubuntu.com/production/apport/bin/apport-retrace ~/4d9d6984-1883-11e4-84c3-fa163e22e467.crash -S /srv/da
  isy.staging.ubuntu.com/production/daisy/retracer/config --sandbox-dir /srv/daisy.staging.ubuntu.com/production/cache/Ubuntu\ 14.10/cache-DhmXbj/sandbox -C /srv/daisy.staging.ubuntu.com/production/cache/Ubuntu\ 14.10/cache-DhmXbj/cache -v -g

  With that bt full would return:

  No symbol table info available.
  Backtrace stopped: previous frame identical to this frame (corrupt stack?)

  However, using apport-retrace without the sandbox-dir command creates
  a more complete backtrace like in http://paste.ubuntu.com/7929061/.

  I've tracked this down to the following from needed_runtime_packages
  in apport/sandboxutils.py:

      # grab as much as we can
      for l in libs:
          if os.path.exists(sandbox + l):
              continue

  There is no check to see if the sandbox version of the library is
  current or not, subsequently the library may be out of date which was
  causing the retrace to fail.

  I've verified this by checking the ctime of the file before and after
  commenting out the "if os.path.exists()" check.
