bootstrap.py fails

[readyready15728]

When attempting to run bootstrap.py the following error is encountered:

error in src/engine/SCons/Action.xml
Traceback (most recent call last):
  File "bin/scons-proc.py", line 108, in <module>
    saxparser.parse(StringIO(input))
TypeError: initial_value must be unicode or None, not str
scons: *** [build/doc/man/builders.man] Error 1
scons: building terminated because of errors.

This issue was however readily resolved by replacing the line saxparser.parse(StringIO(input))
with saxparser.parse(StringIO(unicode(input))).
