It's OK and expected for visitors to return errors when presented with the fuzz test's random data. Since the fuzzer doesn't care about errors, we pass in NULL rather than an Error**. This fixes a bug in the fuzzer where it was passing the same Error** into each visitor, with the effect that once one visitor returned an error, each later visitor would notice that it had been passed in an Error** representing an already set error, and do nothing. For the case of visit_type_str() we also need to handle the case where an error means that the visitor doesn't set our char*. We initialize the pointer to NULL so we can safely g_free() it regardless of whether the visitor allocated a string for us or not. This fixes a problem where this test failed the MacOSX malloc() consistency checks and might segfault on other platforms [due to calling free() on an uninitialized pointer variable when visit_type_str() failed.].
