Can you provide more specific instructions on how to reproduce this crash?  Is simply loading the URL sufficient, or do specific links need to be clicked?

Alas, I could not make a regression test, even after trying hard.

You could write this:

    ASSERT(!m_documentResources.contains(resource->url()) || m_documentResources.get(resource->url()) == resource);

I think it's a little easier to understand.

That's how I wrote it originally, but it was difficult to see why the assertion failed when stopped on it in the debugger.
