string conversion fix on tokenize functrion

[sespindola]

I encountered an error when trying to use js-yaml.
It generates an error on the tokenize function when parsing non-string objects.
I've added a forced string conversion which fixes the problem.
Feel free to pull if you want this.

Can you give an example on where this happens?

I was able to reproduce this bug, but the patch sespindola submitted does not work.

The if statement should read if (typeof str != 'String').

The bug can be reproduced when passing an object to yaml.eval. The object is not casted to string which causes this error:

Object has no method 'replace' at Object.tokenize (/usr/local/lib/node/.npm/yaml/0.1.1/package/lib/yaml.js:74:19)

Two things.

• typeof str will never === 'String' but maybe 'string'
• you should be passing a string to yaml.eval

Agreed.
