Comment 13 fujiwara 2017-09-08 06:13:57 UTC 
I cannot reproduce the backtrace but I think this problem might happen and a patch could avoid it.
Comment 14 fujiwara 2017-09-14 11:00:53 UTC 
The tentative patch is not agreed in upstream.

-    public string get_selected_string() {
+    public string? get_selected_string() {
+        if (!(this is IBusEmojier))
+            return null;
         return m_result;
     }
