tst_examples crashes on CI system

202127f860208c21145e05685bc54219e1655dbd fixes one crash in qtdeclarative, and even appears to fix QTBUG-21995. However every build since has crashes in cleanupNodes() on every example with text - and every test that happens to have text somewhere as well (tested: qquicklistview got exact same backtrace).

sync.profile for qtdeclarative is using an old qtbase until this issue is resolved. When qtbase doesn't break qtdeclarative tests, please return the qtdeclarative sync.profile to refs/heads/master of qtbase.
