** Changed in: qtbase-opensource-src (Ubuntu)
Status: Triaged => Fix Committed
** Description changed:
- What happened:
+ 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) Ensure you are running a wayland session
+ 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
- 6) Notice that the application crashes
- What I expected to happen:
- At step 6 for a file dialog to appear
+ 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 ==
There is a qt bug here "GTK+ dialogs crash on Wayland" -
https://bugreports.qt.io/browse/QTBUG-55583
With what looks like a simple code change that Ubuntu could carry as a patch?
https://codereview.qt-project.org/#/c/179124/
Fedora appear to have fixed the bug in Fedora 25 -

== Debug output ==
When this occurs in the console you see the following:
