Bug description:
Impact
======
The file chooser dialog app for Qt apps will crash the app when trying to use
the file chooser from a Wayland session such as GNOME on Wayland. GNOME on
Wayland is included by default in Ubuntu GNOME.
Test Case
=========
1) Install Ubuntu 17.04 GNOME
2) On the login screen, click the gear button and choose GNOME on Wayland and
log in.
3) Install qtcreator
4) Launch qtcreator
5) Try to do File -> Open File or Project
The file chooser should open without crashing the app
Regression Potential
====================
This fix was included in Qt 5.8. This patch was applied in Debian stretch in
January as part of qtbase-opensource-src 5.7.1+dfsg-3
== Upstream ==
