File 0001-Fix-crash-on-exit-when-using-default-property-aliase.patch of Package libqt5-qtquickcontrols
From 59c6c0e0b1b5b46747595a58e11311b7393d7e70 Mon Sep 17 00:00:00 2001 From: Mitch Curtis <mitch.curtis@qt.io> Date: Tue, 13 Sep 2016 10:23:22 +0200 Subject: [PATCH] Fix crash on exit when using default property aliases with layouts The layout was being destroyed before the text, which meant that the removeItemChangeListener() call never got hit. To ensure that the listener is always removed, loop through each child in QQuickLayout's destructor.
