--- Comment #1 from Vincent Povirk madewokherd@gmail.com 2010-03-30 16:05:32 --- I suspect the problem is fixme:wincodecs:IcoFrameDecode_ReadPixels unsupported bitcount: 0
If you hack IcoFrameDecode_CopyPixels in dlls/windowscodecs/icoformat.c to return S_OK unconditionally, does that get you further?
