+Subject: [PATCH] Fix crash in lastupdate() method
+
+When a RRD database contains floating point values, the
+PyRRD_Int_FromString function returns NULL, which will then be tried
+to be put into a dictionary.
+This operation fails as PyDict_SetItemString does not handle NULL
+and the program crashes with SEGV.
+
+This patch parses the value as a floating point number
+and will add that instead. If the value could not be parsed,
+None will be added instead.
