Somewhat nice that after nearly 10 years something has been done about this.
Yet I strongly suspect that this "cures" just one of the symptoms of a deeper issue, namely some busy waiting whenever a network connection is a attempted but the network or the addressed server is (temporarily) unavailable. See also bug 1107251, bug 683651, bug 562977, and likely several more. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1012858 Title: "Sending of message failed" dialog needs 100% of one CPU as long as it is open.
