SYNTAX_ERR and SyntaxError are different. You need to use 'return throwVMError(exec, createSyntaxError(exec, "..."));'

> Source/WebCore/bindings/v8/custom/V8BlobCustom.cpp:106

Ditto. You need to use 'return V8Proxy::throwError(V8Proxy::SyntaxError, "...");'

The patch looks OK. I think there is no compatibility concern (Firefox and IE do not implement the Blob constructor) but let's wait for a comment from File API folks.

kinuko-san: Does this change look OK?

It is so strange. 
This patch can result in 2d.gradient.radial.cone.top.html test failed.
