If you run your dev box and there is no internet connection you will get loads of

[abrt] pyzor: client.py:72:send:gaierror: [Errno -2] Name or service not known

emails. This can go into a email loop and freeze your system.

To stop this you need to modify the /usr/lib/python2.7/site-packages/pyzor/client.py script to handle the error :

def run(self, server, varargs, kwargs=None):
    if kwargs is None:
        kwargs = {}
    message = "%s\t" % str(server)
    response = None
    try:
        response = apply(self.routine, varargs, kwargs)
        self.handle_response(response, message)
-    except (CommError, KeyError, ValueError), e:
+    except (CommError, socket.error, KeyError, ValueError), e:
        sys.stderr.write(message + ("%s: %s\n"
                                    % (e.__class__.__name__, e)))
        self.all_ok = False

Change line 815: except (CommError, KeyError, ValueError) to (CommError, socket.error, KeyError, ValueError) ie add the socket.error catch.
