Bug description:
  In the event that a distribution upgrade crashes apport_crash from
  DistUpgradeApport.py is called which then tries to attach files to the
  crash report (_apport_append_logfiles).  However, key name for the
  file attachment in the report is formed using the directory '/var/log
  /dist-upgrade' which includes '/' in the key name.  This causes apport
  to crash as seen here:

  Traceback (most recent call last):
    File "DistUpgrade/DistUpgradeApport.py", line 120, in <module>
      apport_crash(None, None, None)
    File "DistUpgrade/DistUpgradeApport.py", line 57, in apport_crash
      _apport_append_logfiles(report)
    File "DistUpgrade/DistUpgradeApport.py", line 30, in _apport_append_logfiles
      report[ident] = (open(f), )
    File "/usr/lib/python2.7/dist-packages/problem_report.py", line 561, in __setitem__
      assert k.replace('.', '').replace('-', '').replace('_', '').isalnum()
  AssertionError

  because '/' is not alpha numeric.  Apport should probably replace '/'
  but u-r-u / update-manager previously attached these files with
  specific names, like VarLogDistUpgradeApttermlog.txt, and the u-r-u /
  update-manager package hooks uses those same names.  Subsequently, I
  thought it best to fix u-r-u to use the same key / attachment names.

  = Impact =
  When update-manager / u-ru crashes we are not receiving the log files we want from apport and probably we aren't even receiving crash reports from it.

  = Test Case =
  A simple test case is to manually call DistUpgradeApport.py:

  1) touch /var/crash/_usr_bin_update-manager.0.crash
  2) sudo python /usr/lib/python2.7/dist-packages/DistUpgrade/DistUpgradeApport.py (you need to do this via sudo to access the files)

  With unfixed version of DistUpgradeApport.py you'll receive an
  assertion error, with the fixed version you won't.  Additionally, if
  you look in '/var/crash' you'll find a file named '_usr_bin_update-
  manager.0.crash' which will include attachments and key names like
  'VarLogDistUpgradeApporttermlog.txt'.
