Pybootchartgui: UnicodeDecodeError

[AzureCrimson]

Cause of problem

My dmesg contains escape characters, preventing pybootchartgui from processing bootchart logs on my machine.

---

Suggested fix

Replace

bootchart/pybootchartgui/parsing.py

Line 529 in 331ada0

for line in file.read().decode('utf-8').split('\n'):

with

for line in file.read().decode('utf-8', 'ignore').split('\n'):

or another Python UnicodeDecodeError handling method.

Failing case

stripped dmesg output
