"TypeError: coercing to unicode" when piping colored output

[ghost]

When I use octogit in a pipeline

$ octogit issues | less

I get the following traceback:

Traceback (most recent call last):
  File "/home/dialelo/.virtualenvs/o/bin/octogit", line 8, in <module>
    load_entry_point('octogit==0.1.3', 'console_scripts', 'octogit')()
link. https://github.com/alejandrogomez/turses/issues 

  File "build/bdist.linux-i686/egg/octogit/cli.py", line 126, in begin
  File "build/bdist.linux-i686/egg/octogit/core.py", line 252, in get_issues
TypeError: coercing to Unicode: need string or buffer, int found

The line that causes the error:

puts('listing all {0} issues.'.format(colored.red(get_number_issues(json_data)))) 

If I remove the colored.red function call it does not happen.

I fixed this issue; but this breaks the structured layout of the issues list. It not doesn't throw an error, but less isn't very usable with octogit in this manner.
