python: str.decode() doesn't like kwargs in python 2.5

Recent changes introduced lots of unicodification of strings, mostly in
the form of .decode('utf-8', errors='ignore'). However, python 2.5 does
not like the errors keyword argument and complains. It does work when
used as a simple arg though, so that's what this patch does.
