This is a no-go. Do you need to wait for some event?

[Lei Zhang, 2010/12/02 18:06:12]

I'm already waiting with WaitUntilTabCount() - I see the tab coming up, but for
some reason the TabProxy doesn't return the title properly. I can try
BrowserProxy::WaitUntilTabCount() and see if that makes a difference.

I think the main problem is that the test doesn't wait for the load to finish in
the second tab.
