Updating to version 0.4.0. Tests works longer. Strange STDERR output.

Hi. After updating xolvio:webdriver I got strange STDERR output. And tests works slower (I'm using single mirror to execute tests). 237s for 0.4.0 and 41s for 0.3.1.
Here is STDERR output:

sounds like you have a missing callback somewhere in cucumber
