Can't rename a file?

[jpetitcolas]

I try to rename a file using:

yield fs.rename(src, dest);

Yet, I got the following error:

TypeError: You may only yield a function, promise, generator, array, or object, but the following object was passed: "undefined"
      at next (/home/jpetitcolas/dev/xxx/node_modules/koa/node_modules/co/index.js:101:25)
      at onFulfilled (/home/jpetitcolas/dev/xxx/node_modules/koa/node_modules/co/index.js:69:7)

fs.js:77
      throw err;  // Forgot a callback but don't know where? Use NODE_DEBUG=fs
            ^
Error: EXDEV, rename '/tmp/lazg2qxdek4kj4i/file.png'

I am using Koa 1.0.0 and co-fs 1.2.0. Any idea? :)
