I don't pretend to be a developer, but that seems to make sense only from the amount of those messages seen. As I mentioned previously, I see the messages only with KDE and not Xfce or window managers. That indicates something peculiar to KDE/Qt. Qt probably needs patching eventually. At least, that is the opinion of a few people who questioned whether proceeding with updating 3.5.10 is worthwhile. If patching is required then sounds like a project for 3.5.13 and not 3.5.12?
