New submission from Seyeong Kim <seyeong.kim at canonical.com>:

In some circumstances using unicode, formatwarning show me ascii error

so I should prefix on below line to remove this crash
s =  "%s: %s: %s\n" % (lineno, category.__name__, message)
to
s =  u"%s: %s: %s\n" % (lineno, category.__name__, message)

below are logs
