This was also reported at http://code.google.com/p/chromium/issues/detail?id=89155.

It appears this is happening when an EventSource reconnect timer triggers after a navigation away from the current page has begun. In this case, SubresourceLoader::create() will return 0, and EventSource ends up thinking a request is in-flight but has a null m_loader.

I have a fix (don't set "m_requestInFlight = true" in connect() if ThreadableLoader::create() returns 0), but I don't have a good test reduction because it's timing-dependent.
