+        [Qt] JavaScript prompt is currently broken
+        https://bugs.webkit.org/show_bug.cgi?id=30914
+
+        In r52152 a patch was landed to convert a null QString
+        to an empty WebCore::String in case the prompt was accepted
+        but the default implementation returned the null QString.
+
+        The patch tried to avoid assign to result twice and
+        was not checking the QString if it is null but the default
+        value. This lead to always returning an empty string on
+        successful prompts. Fix it by checking the variable 'x'
+        for isNull.
+
+        The manual test case used didn't cover the case of non
+        empty input, replace it with an automatic test case that
+        should cover all cases.
