Public bug reported: Using unity8 from https://launchpad.net/~canonical- qt5-edgers/+archive/qt5-beta-proper together with Qt 5.1.1, which following packages:
unity8 1:7.81.3+13.10.20130905.2 -0+201309091433~302~ubuntu13.10.1 libqt5core5:armhf 5.1.1+dfsg-2ubuntu1~saucy1~test5 libqt5opengl5:armhf 5.1.1+dfsg-2ubuntu1~saucy1~test5 Qt5.1.1 based build: http://s-jenkins:8080/job/ubuntu-touch-image-saucy-qt51/5/artifact/saucy-preinstalled-phablet-armhf.zip Steps to reproduce: 1 - Boot the phone 2 - Open an app (e.g. browser) 3 - Get back to the shell 4 - Close the app Stacktrace: Program received signal SIGSEGV, Segmentation fault.
