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)
There is a combination of build failures (on armhf and amd64) and a success (i386) with unity-scopes-shell when built against Qt 5.2:
