Description Chris Marrin 2011-05-04 11:38:24 PDT
PlatformCALayer ::replaceSublayer occasionally crashes because the current layer doesn't have a superlayer. I believe this is a benign case that happens when we are restructuring the tree. But currently it crashes. I will add protection against the null pointer and see if this avoids any other problems.

You could leave the assertion in since it would be nice to know when this happens.
