ImageDecoder was renamed to ScalableImageDecoder because a multiplatform ImageDecoder class added, and ScalableImageDecoder inherits from it.

But I think you're right and this is the fix for the problem. I hadn't realized at all that those locks were added, and I was wondering why I couldn't reproduce the problem with current ToT. And I guess this is the reason.

I'll backport the locks patch and check whether they fix the crash.

Thanks for your help Fujii!!
