Snap-debug.security scanlog crashes with UnicodeDecodeError

[Carlo Lobrano]

How I reproduced it:
================

1. sudo snappy install snappy-debug
2. sudo snappy-debug.security scanlog

Traceback
=========

(amd64)ubuntu@localhost:~$ sudo snappy-debug.security scanlog
kernel.printk_ratelimit = 0
Traceback (most recent call last):
  File "/apps/snappy-debug.canonical/0.3/bin/snappy-security-scanlog", line 478, in <module>

    data = self.read(readsize, firstline=True)
  File "/usr/lib/python3.4/codecs.py", line 497, in read
    newchars, decodedbytes = self.decode(data, self.errors)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf3 in position 0: invalid continuation byte
