Text input on Android causes instability

It seems that using TextInput in some scenarios causes instability on Android (application crashes, crash log attached). This happens often on the "real" application I'm working on - however I was also able to reproduce a crash with a simple test application (attached qml file of a slightly modified hello world).

The crash is a bit difficult to reproduce with the test application, at least manually, but it seems that pushing an item on Stack, focusing/writing on a TextInput, popping with back-button & repeating fast enough will at some point cause it. Unfortunately it happens much more easily on the "real" application.

In addition, I have a feeling that this didn't happen so much before Qt 5.3.2. I don't know it the fact that the stack item in the example being anchored and giving warning about it in the logs has anything to do with the problem
