What steps will reproduce the problem?

1. Instantiate webdriver
2. launch url of application under test
3. find image in browser window

What is the expected output? What do you see instead?
NullPointerException while trying to find image on screen

What version of the product are you using? On what operating system?
Sikuli 1.0 Java API / Windows 7

Please provide any additional information below.
When I run the same steps with Sikuli opening browser(using API.browse(url)), it works fine. Only when Webdriver launches browser, test fails.
