--- Comment #2 from luke at ubuntu-mate.org ---
Returning null makes sense when the title is changed but remains the same as the last one (e.g. "One" → "One"). Currently, an application would still receive the signal and take action (in this case, print to the terminal) whereas the behaviour in 2.12 did not trigger (a workaround was getting the JavaScript to set the title to null after xx milliseconds).

However, while a null can be ignored, the problem lies that clicking any sequential links does this: "One clicked" → null → "One clicked", causing the application to trigger its action twice.

An ideal solution would be to only notify a title change once, so it's compatible with 2.12 behaviour: "One clicked" → null ... "Two clicked" → null ... etc
