Title:
  apport hook fails in add_info with TypeError: 'str' does not support
  the buffer interface

Status in apport package in Ubuntu:
  Fix Released
Status in apport source package in Xenial:
  In Progress

Bug description:
  Impact
  ------
  Some apport package hooks are not able to check the contents of log files for errors, e.g. looking for hard disk errors in ubiquity install logs, so we may be getting crash reports that we don't want.

  
  Test Case
  ---------
  ⟫ ubuntu-bug ubiquity
  dpkg-query: aucun paquet ne correspond à ubiquity
  ERROR: hook /usr/share/apport/package-hooks/source_ubiquity.py crashed:
  Traceback (most recent call last):
    File "/usr/lib/python3/dist-packages/apport/report.py", line 197, in _run_hook
      symb['add_info'](report, ui)
    File "/usr/share/apport/package-hooks/source_ubiquity.py", line 61, in add_info
      if 'Buffer I/O error on device' in syslog:
  TypeError: 'str' does not support the buffer interface

  With the version of the package in the archive you'll see the above
  Traceback, with the version of proposed you will not.

  Regression Potential
  --------------------
  The change uses a try, except clause to do the decoding of the log file so there should be little chance of a regression.
