x86 builds of libusermetrics seem to be fine now that I supplied a qdjango rebuild, but armhf is failing:

https://launchpadlibrarian.net/162354187/buildlog_ubuntu-trusty-armhf.libusermetrics_1%3A1.1.1%2B14.04.20131125-0~145%2B201401131441~ubuntu14.04.1_FAILEDTOBUILD.txt.gz

It's not yet possible to upgrade to Qt 5.2 easily, because of build failures like this bug report that prevent full dist-upgrade from the PPA. Therefore, if you are using chroot / virtual env or otherwise ok with removing Unity temporarily, do sudo apt-add-repository ppa:canonical-qt5-edgers/qt5-beta2 and see https://lists.launchpad.net/ubuntu-phone/msg05690.html for an alternative upgrade method (the quoted part) that can be used already to setup Qt 5.2 environment. If interested, see the dependency chain at http://pad.ubuntu.com/qt52-dependencies)

If this is an upstream bug, a simple test case could be submitted to https://bugreports.qt-project.org/. The qtdeclarative in the PPA is already a recent snapshot from upstream stable branch, to fix some known bugs.
