Nit: bug number?

I think this merge was a bit too automatic ;-). Don't you mean:

void SourceBuffer::remove(double start, double end, ExceptionCode& ec)

> Source/WebCore/Modules/mediasource/SourceBuffer.cpp:176
> +        es.throwDOMException(InvalidAccessError);

ec = INVALID_ACCESS_ERR;

> Source/WebCore/Modules/mediasource/SourceBuffer.cpp:184
> +        es.throwDOMException(InvalidStateError);

ec = INVALID_STATE_ERR;

Clearing r+ flag; new patch is significantly different enough from previous patch to warrant re-review.

You NULL check m_source above, do you need to so so here as well?

No, the isRemoved() statement above is effectively a NULL check.
