           Summary: ArgumentCoder for WebCore::Animation encodes a bool
                    which is never decoded
           Product: WebKit
           Version: 528+ (Nightly build)

The encode function for WebCore::Animation encodes a bool as the last entry (currently L1093 in WK2/Shared/ArgumentCoders.cpp):

encoder->encodeBool(animation->isNoneAnimation());

This value is never read out in the decode function causing updates with many animations to go awry. I noticed this in my own WK port, but imagine it would break for Qt, too (though I haven't tested). The morphing power cubes demo reliably causes the issue to crop up for me.
