# When we build on Ubuntu on 14.04 and run on 17.10, the app fails to start

# > This application failed to start because it could not find or load the
# > Qt platform plugin "xcb" in "". Available platform plugins are:
# > eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

# We also don't want to ship libgio-2.0.so because it is usually present.
# What's more, if we ship libgio without libgtk, then segmentation faults
# occur when freezing on Ubuntu 14 and running on Ubuntu 16. The reason for
# this is that libgio depends on libgtk. Because we don't ship libgtk, this
# loads the user's libgtk, which is incompatible between Ubuntu 14 and 16.
