Summary: property_get on $this->undefinedvariable
Description:
property_get -n $this->somethingnonexistent crashes the debugger. In source
code:

retval = fetch_zval_from_symbol_table(st, keyword, keyword_end - keyword,
type, current_classname, cc_length TSRMLS_CC);
current_classname = fetch_classname_from_zval(retval, &cc_length
TSRMLS_CC);
if (retval) {
        st = fetch_ht_from_zval(retval TSRMLS_CC);
}
keyword = NULL;

As retval may be nill then fetch_class_name crashes.
If this issue is fixed then for some weird reason
        res = zend_eval_string(eval_string, ret_zval, "xdebug eval" TSRMLS_CC);
crashes in _xdebug_do_eval.
