I think that is one of the many bugs that has been fixed in the past years since that version was released. I suggest that you open a bug tracker with ubuntu. Maybe they solve this by re-creating the packages with recent builds. I am not bashing: that's most probably really the solution, and it would be great if they did. AFAIK there are recent .deb packages, so this should not cause too much trouble to them... I understand this is not the answer you were looking for. Sorry for that. But even if I dug out which patch you need, it wouldn't go into the ubuntu package, so there is no point in that. If you can build from source, you can do that, but then simply use the most recent released version (4.8.somewhat for the v4 tree). Note that v4 is officially too old to be supported by the project itself. We are right now at 6.2.2.
