Bug Description

I'm getting a crash relatively easily with webbrowser-app on Qt 5.1.1. Backtrace from x86 (where it happens right after loading ubuntu.com, on device I can browse a little while but it seems to be similar place where it crashes, ie. QSGNode):

If you need to do something Qt 5.1 specific, see eg. https://code.launchpad.net/~aacid/unity8/supportqt51/+merge/177365 on how to #ifdef on the Qt version to support both 5.0.x and 5.1.x with different codepaths.

Apport collect coredump etc. in bug #1217694.

One can install Qt 5.1.1 snapshot with:
sudo apt-add-repository ppa:canonical-qt5-edgers/qt5-beta2
sudo apt-get update
sudo apt-get dist-upgrade

Luckily this seems to go away with webbrowser-app rebuild (I think which is something that was needed before as well). I put a webbrowser-app rebuild added with epoch in version to beta2 PPA.
