I don't understand. When I run the test case, I get this stack for an assertion failure:


#0  0x0000000000c46dce in WebCore::getImageData<(WebCore::Multiply)0> (rect=..., bitmap=..., size=...)
    at third_party/WebKit/WebCore/platform/graphics/skia/ImageBufferSkia.cpp:160
#1  0x0000000000c4588d in WebCore::ImageBuffer::getPremultipliedImageData (this=0x7fffecf12200, rect=...)
    at third_party/WebKit/WebCore/platform/graphics/skia/ImageBufferSkia.cpp:199
#2  0x000000000102453b in WebCore::FEGaussianBlur::apply (this=0x7fffed3c0460, filter=0x7fffed41a6e0)
    at third_party/WebKit/WebCore/platform/graphics/filters/FEGaussianBlur.cpp:122

This doesn't look like what you're changing at all. I see an assertion failure later when checking the format of the empty bitmap (which is nothing since it's empty). Can you post the stack of the crash you're seeing and/or explain in more detail what the exact problem is?
