retracer needs to hint at MIME type text/plain

[Kees Cook]

Binary package hint: apport

Related to bug 34758, it seems that it is the duty of the file uploader to hint to librarian what mime type an attachment is. To avoid things like this:

http://librarian.launchpad.net/7689757/%3Cfdopen%3E (via bug 115332)

The retrace needs to hint a mimetype of text/plain for the retraces. (Note that this appears to already happen correctly for the initial report attachments.)

 apport (0.81) gutsy; urgency=low
 .
   * apport/report.py: Remove '[apport]' default bug title prefix. (LP: #94819)
   * apport/crashdb_impl/launchpad.py: Tag new bugs with
     'apport-<problemtype>'. This replaces the former '[apport]' prefixing.
   * debian/local/setup-apport-retracer: Specify a path in '.' command and
     use sh again. Yay for me needing three attempts before actually RTFMing
     how '.' works (which is really nasty and strange IMHO).
   * bin/apport-chroot: Fix symlinks before repackaging the chroot tarball in
     'install' and 'installdeb' modes.
   * debian/local/setup-apport-retracer: Install python-libxml2 and python-apt.
   * bin/launchpad-crash-digger: Supply --auth instead of the deprecated
     --cookie to apport-chroot.
   * bin/apport-chroot: Fix identifier name in command_retrace().
   * debian/local/setup-apport-retracer: Set APPORT_CRASHDB_CONF to the local
     crashdb.conf.
   * bin/apport-chroot: Unset APPORT_CRASHDB_CONF for login and retrace.
   * bin/launchpad-crash-digger: Check the release of a bug and whether we have
     a chroot for it before untagging it. This avoids loosing tags for bugs we
     do not yet have a working retracer chroot for.
   * bin/apport-retrace: Do not abort with an exception if package installation
     fails. Give a proper error message instead and point to -u. (LP: #115681)
   * apport/crashdb_impl/launchpad.py, update(): Create a temporary directory
     and use proper file names for the new attachments. With TemporaryFile(),
     attachment file names ended up as '<fdopen>'. (LP: #115347)
   * apport/report.py, add_os_info(): Add field 'NonfreeKernelModules' which
     lists loaded kernel modules which do not have a FOSS license. This is
     particularly helpful for quickly checking for restricted graphics drivers.
     (LP: #103239)
   * apport_python_hook.py: Move the apport.* imports into the try: block and
     move the likely_packaged() test to the top, to avoid importing
     apport.report and creating a Report object for non-packaged scripts. This
     makes the entire code more efficient and robust against errors in the
     apport modules. (LP: #109955)
   * apport/report.py, add_gdb_info(): Intercept OSError from gdb invocation
     (which might be segfaulting itself) and just do not put any gdb output
     into the report. The automatic retracers can try their luck again.
     (LP: #112501)
   * bin/apport-retrace: Fix handling of packages which are still known to
     /var/lib/dpkg/status, but do not have an apt record any more; treat them
     like virtual packages and just issue a warning instead of falling over.
     (LP: #107474)
