Greetings Adam,

(In reply to comment #5)
> It looks similar to problems we had with PNGs.  In that case, we were trying to apply some image transformation (Grayscale => RGB) twice.  Should be easy to narrow down by commenting out code.

Yes. This JPEG is a CMYK JPEG and JPEGDecoder applies CMYK->RGB conversion. (Unfortunately, I'm not sore who uses the ColorSpace object and applies another color conversion.) Is it OK to call 'ImageDecoder::setIgnoreGammaAndColorProfile(true)' also in this case as you did for Bug 49950 <http://webkit.org/b/49950>?

Regards,

Hironori Bono
