+ Reviewed by Keith Miller.
+
+ Symbol.prototype.description was implemented in r232404, but has one small bug:
+ It should return undefined for a null symbol.
+
+ * runtime/Symbol.cpp:
+ (JSC::Symbol::description const):
+ * runtime/SymbolPrototype.cpp:
+ (JSC::symbolProtoGetterDescription):
+ Address the null symbol case.
