apport-qt needs to fix pyqt UTF-8 string handling

I can reproduce this.

<Riddell> pitti: wouldn't entirely surprise me, pyqt has some strange behaviour with unicode strings
<Riddell> pitti: it's entirely fixable though, I just need to copy the code from ubiquity or dist-upgrade tool or whatever

I think I fixed at least most of the problems (if not all) now. Please let me know if something is still missing in the version that I'll upload soon.

 .
   * gtk/apport-gtk.glade: Reintroduce window titles. Since the crash
     notifications are like alerts, title have been removed recently to comply
     with Gnome HIG standards, but then the user will get 'nameless window'
     buttons in the task bar. Let's have the smaller evil then. (LP: #87164)
   * apport/packaging.py: Add get_architecture() interface for determining the
     architecture of a particular package (which might not match the overall
     system architecture on multiarch-capable systems, e. g. an i386 Firefox
     package installed on amd64).
   * backends/packaging-dpkg.py: Implement get_architecture() and add test
     case.
   * apport/report.py, add_package_info(): Add Architecture: field.
     (LP: #87424)
   * apport/ui.py: Already mark report as seen when we load it, not just in the
     information collection thread. That way, reports will only be shown once
     on systems which have /var/crash mounted noatime, too. (LP: #85809)
   * apport/fileutils.py, mark_report_seen(): If os.utime() fails, and opening
     the report file for reading does not change the atime (happens with
     noatime mount option), don't throw an exception, just delete the report.
     (other aspect of LP: #85809)
   * qt4/apport-qt: Wrap gettext() into an unicode(str, 'UTF-8') call,
     otherwise all non-ASCII unicode strings are broken. (LP: #87757)
