It seems it's not completely stalled, there's activity in another bug
report linked from the first one, and a claimed partial fix.

I don't have a 14.04 machine to test on right now, so could someone else test:
sudo apt-add-repository ppa:canonical-qt5-edgers/qt5-proper
sudo apt update
sudo apt dist-upgrade

Notes:
- The patch needed changes especially for 14.04's Qt 5.2.1, I'm not sure if it's functional still or if I broke something in the process
- The qtbase for 14.10 (which I could have tested) failed one unit test with a crash, which could be caused by the patch since it has not happened before.
- We will eventually get the fix anyway with 5.3.2 to 14.10 or 15.04 since it was included in upstream's 5.3.2 branch, after which a backport to 14.04 LTS is feasible even if we wouldn't cherry pick it for current 5.3.0
- See the builds and patches for 5.3.0 and 5.2.1 respectively at https://launchpad.net/~canonical-qt5-edgers/+archive/ubuntu/qt5-proper/+packages - feel free to get the original upstream patch (https://codereview.qt-project.org/#/c/93402/) and try backporting yourself in case some of my choices were erronous
