Cura won't open

[bbaumg]

Application Version: 2.4.0
Platform: Ubuntu 16.10 (Default Install)

Steps to Reproduce:
Default install of Ubuntu 16.10 from ISO into a virtualbox instance.
Install Cura from PPA... All install commands below:
sudo apt-get update -y && sudo apt-get install -y vim openssh-server wget git-core htop && sudo apt-get upgrade -y && sudo add-apt-repository ppa:thopiekar/cura --yes && sudo apt-get update && sudo apt-get install cura -y && sudo apt-get install cura-extra-plugins-all -y && sudo apt-get autoremove -y && sudo reboot

Actual Results:

When cura attempts to open, the splash screen will show the following messages:
a. Loading machines...
b. Loading interface...
Sometimes Ubuntu will give a crash message, sometimes not. There is no other feedback and cura will not start.
When reviewing the log file /var/username/.local/share/cura/cura.log the final set of entries after machine related are:

Expected results:

This is a known issue. It is caused by Canonical manually patching the Qt packages for Ubuntu. See #1094 for more details.
