I think this could be stated a little more clearly. Something like:

Bail out when we fail to allocate an Ewk_Frame_Smart_Data object rather than continuing on as if the allocation had succeeded.

> Source/WebKit/efl/ewk/ewk_frame.cpp:184
>          sd = (Ewk_Frame_Smart_Data*)calloc(1, sizeof(Ewk_Frame_Smart_Data));
> -        if (!sd)

>              CRITICAL("could not allocate Ewk_Frame_Smart_Data");
> -        else
> -            evas_object_smart_data_set(o, sd);
> +            return;
> +        }

Is this really a condition we expect to occur? Will we really continue to function correctly even if we return early from this function? We don't check for allocation failures in most of WebKit/WebCore, so I assume that if we're really in an out-of-memory situation we'll just crash a little later.
