The crash is an assertion failure, so it's not surprising that it only occurs in debug builds. Assertions aren't compiled into release builds.

Sometimes, looking at svn blame to see when the assertion was added help one figure out what it is about. In general, asking a renderer-related question like isFocusable() needs finished layout indeed - e.g. display:none makes a node unfocusable, but before layout (recalcStyle?), the renderer doesn't know that.
