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
