ASSERTION FAILED: destx >= 0
(../../WebCore/platform/graphics/cairo/ImageBufferCairo.cpp:223 void WebCore::putImageData(WebCore::ImageData*&, const WebCore::IntRect&, const WebCore::IntPoint&, WebCore::ImageBufferData&, const WebCore::IntSize&) [with WebCore::Multiply multiplied = (WebCore::Multiply)1u])

Program received signal SIGSEGV, Segmentation fault.

Gtk, but I think we have this ASSERT on all platforms, since all platforms just copied the code from Mac.
