Bug Description

The latest UITK release (1.3.2190+16.04.20170327) causes this unity8 test crash on xenial/i386:

#0 0xf5a4418f in QQmlBinding::QQmlBinding(QV4::Value const&, QObject*, QQmlContextData*) () at /usr/lib/i386-linux-gnu/libQt5Qml.so.5
#1 0xeb47a95b in UCStyleHints::_q_applyStyleHints() () at /usr/lib/i386-linux-gnu/libUbuntuToolkit.so.5
#2 0xeb4a4464 in () at /usr/lib/i386-linux-gnu/libUbuntuToolkit.so.5

[...]

Downgrading to 1.3.2184+16.04.20170306build1~~xenialoverlay1~1 fixes the issue.

To reproduce:
* install unity8-tests
* $ sh /usr/lib/i386-linux-gnu/unity8/tests/scripts/gdbtestShell.sh
* CRASH

However, processing it in order to get sufficient information for the
developers failed (it does not generate a useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system

This is because the latest UITK did not get rebuilt after the qtdeclarative landed, so it is broken in the same way UITK was with the qtdeclarative silo before 1.3.2184+16.04.20170306build1~~xenialoverlay1~1 rebuild was added to the silo.

A rebuild will come from https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2699/+packages
