Bug description:
  [impact]

  sosreport plugin(s) fail

  [test case]

  run sosreport, then extract the captured report and check the sos_logs
  /logs-plugin-errors.txt file for output like:

  Traceback (most recent call last):
    File "/usr/share/sosreport/sos/sosreport.py", line 1300, in collect
      plug.collect()
    File "/usr/share/sosreport/sos/plugins/__init__.py", line 877, in collect
      self._collect_strings()
    File "/usr/share/sosreport/sos/plugins/__init__.py", line 860, in _collect_strings
      (content.splitlines()[0]).decode('utf8', 'ignore'))
  AttributeError: 'str' object has no attribute 'decode'

  
  one of the ways to trigger this is for sosreport to gather a file that is larger than its max size to gather, for example log files over its --log-size limit.  To reproduce this way, first make sure one or more of the sosreport-gathered log files are over 1m, e.g. on a newly-installed system (where log files are small) you could do this just to generate logs:

  # udevadm control -l 7
  # for n in $( seq 1 50 ) ; do udevadm trigger ; done

  after that, /var/log/syslog should be larger than 1m.  Then run
  sosreport and limit its log file size to 1m:

  # sosreport --log-size 1

  The resulting sosreport will contain the error while trying to gather
  the syslog.

  
  [regression potential]

  the currently failing plugins fail to gather any of their data, so
  there is not much regression for them, but this change has the
  potential to affect any plugin and prevent data gathering.
