There have been several notorious bugs throghout Qt 5.4, 5.5 and 5.6 development cycles that cause these kinds of crashes when monitors change or "disappear". Most Qt 5.6 fixes have been backported to the Ubuntu's Qt 5.5 version in 16.04 LTS, so it would be useful to upgrade to 16.04 LTS and see if the behavior would be better now.
