Title:
  Running Qt apps inside a 18.04 container crashes

Status in qtbase-opensource-src package in Ubuntu:
  Confirmed

Bug description:
  What happened:
  1) Install a container system (eg Docker, LXD) - I'm using Docker
  2) Create a container which is Ubuntu 18.04
  3) Install a Qt app, eg qtcreator, inside the container
  4) Run the container so that it shows the hosts X11 socket
  5) Notice that the application fails to start

  What I expected to happen:
  At step 5 for the application to start.

  Note that the same steps work fine for Ubuntu 16.04 and 17.10 - and if
  it matters my host is 17.10.

  Here is a stacktrace of the crash
  https://pastebin.ubuntu.com/p/WKKGmxqqSx/

  Here is a Dockerfile that reproduces the issue
  https://pastebin.ubuntu.com/p/nzmJRfPYVc/ to use this make a
  Dockerfile in an empty folder with the pastebin contents, then simply
  run the following commands in that folder

  $ sudo apt install docker.io
  $ sudo docker build -t qtbug .
  $ sudo docker run --rm -ti -e DISPLAY --net=host --cap-add=SYS_PTRACE 
--security-opt seccomp=unconfined qtbug

  This should enter you into the gdb session.

This bug is still preventing Qt apps from being run on Core18 snaps. I'm
assuming we're blocked on
https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1755250 ?

Status in qtbase-opensource-src package in Ubuntu:
  Confirmed

Bug description:
  The statx(2) system call is a relatively new addition and has not seen
  widespread use. As such the seccomp filer used by snapd to confine
  application processes does not currently permit it. While addressing
  the bug in snapd is in progress we wanted to contribute a fix to the
  package so that all snaps built with Qt from the Ubuntu archive will
  automatically benefit and behave correctly.
