Comment 42 for bug 1257791

Ok, I think we have a culprit. I flashed my phone cleanly with 20131204 and downgraded only libqt5quick5 from https://launchpad.net/ubuntu/+source/qtdeclarative-opensource-src/5.0.2-6ubuntu4/+build/5094593/+files/libqt5quick5_5.0.2-6ubuntu4_armhf.deb and the backspace and enter key works okay again.
