I'd rather use the version in the current repository:
wget 
https://raw.github.com/wbsoft/frescobaldi/master/frescobaldi_app/indent.py

Actually you'd better download all the source, as indent.py depends on 
some internal modules:

import ly.lex
import ly.lex.scheme
import cursortools
import tokeniter
import variables

I get the same in Python 2.7.3.

I think that the error is explained here:
http://docs.python.org/release/3.0.1/whatsnew/3.0.html#text-vs-data-instead-of-unicode-vs-8-bit

As a quick solution, you can try to update indent.py to python3:
2to3 indent.py

then use:
python3 indent.py -t 2 file.ly

The error goes away... but I'm not sure that the script actually works 
this way: I've tried to set -t 4 (all my ly files have 2 space 
indentation), but nothing changes.

PS I'm not a coder :-)
