Backporting commit 1f39650

Hi. I tried to include 1f39650 commit[1] to QT from Trinity 3.5.13. Compilation went without problems. But after installing an updated version of QT began to fall almost all programs. Please, you have some advice? 1f39650 depends on a previous commits? Should I report it as a separate bug? Backtrace attached...
