Description
QtCreator will crash when opening a malformed `ui.qml` file (the QML file has a problematic "property" field, see below)
Even though the QML is problematic, QtCreator should not crash.
Changing the "=" to ":" makes it work again (since the original one is not following the QML syntax).
Digging further, gdb will produce the following backtrace:
