+Subject: [PATCH] fix: QVariant should be created with
+ QMetaProperty::userType()
+
+QMetaProperty::type() always returns QVariant::UserType for any user-defined
+type. So QVariant of type id 1024(QVariant::UserType) is always created instead
+of the right type whose type ID is returned from QMetaProperty::userType().
+Creating QVariant with wrong type may crash the process.
+
+Fixes RHBZ#1892710
+
+Log: QVariant should be created with QMetaProperty::userType()
