> Omnibox: Possibly Fix Rare OpenMatch Crash
> 
> The associated bug seems to imply a crash on this line

> This change corrects the part of the test that may fail

> I think controller_ is always valid (the rest of the edit
> model code use it without testing it for non-NULL).
> But I see at least two places in OmniboxEditModel that
> test for the non-NULLness of controller_->GetWebContents().
> Hence, I think it might be able to be NULL, so this
> change adds a test for it here too.

> TEST=new code compiles
