Bug description
The error is being triggered when opening flatpak applications (and maybe on normal applications as well, but I must confirm):
Gtk-Message: 18:18:47.154: Failed to load module "xapp-gtk3-module"Steps to reproduce
Try to run a flatpak application through the terminal with the command flatpak run <application id>, for example, I got this error while running insomnia flatpak run rest.insomnia.Insomnia (please remember that the app must be installed before running the command) and you will see the error in the logs.
Expected behavior
The module should be loaded successfully.
Additional information
I don't know what are the consequences of this error, but I also noted that it might be related to some dependency conflict between the Mint Faye packages for the xapp lib and Debian packages for lib xapp. For example here someone suggested installing the xapp package with the command apt install xapp but the following is shown:
Package xapp is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
xapp-sn-watcher:i386 libxapp-gtk3-module:i386 xapp-sn-watcher libxapp-gtk3-module
E: Package 'xapp' has no installation candidate
Or if you try to install the package libxapp-gtk3-module (which seems to be the root of the problem):

The package libxapp-gtk3-module I suspect should be installed on the system but it is not being completely installed because of a conflict with the libxapp1:amd64 2.6.1+faye package while trying to set /etc/X11/Xsession.d/80xapp-gtk3-module.

Don't try to install libxapp-gtk3-module. It's a Debian package, that module is already installed on your system (or should be):
You can ignore the error message on flatpaks. Flatpaks don't have access to the host root, but they're picking up the GTK3_MODULES environment variable when they get launched.
This is harmless, the module is not required. Make sure you end up with xapp 2.6.1+faye packages after your messing around or you may have further issues.

I stumbled upon this closed issue because I am getting this error when I try to run
ubuntu-bugfrom the console and after that, I get an error message in the console:and an error window "The application Settings has closed unexpectedly".
I do not have
/usr/lib/x86_64-linux-gnu/gtk-3.0/modules/libxapp-gtk3-module.soon my system and I was able to install this library withsudo apt install libxapp-gtk3-module.mtwebster commentedon Aug 15, 2024
try running:
then run the program.
As I mentioned above, it shouldn't crash anything, it's just a poorly-worded warning. Also, unless you're on Ubuntu, it may not run anyhow.

Thank you for your recommendation. I am on Ubuntu 24.04. After installing
libxapp-gtk3-moduleI was no longer getting the Gtk-Message error, even when running other applications that produced it before (one of themdconf-editor). UnsettingGTK3_MODULESdid not make any difference after that. But when runningubuntu-bug, I still get "The application Settings has closed unexpectedly" pop-up. I guess, it must be unrelated toxapp-gtk3-module.Moini commentedon Sep 30, 2026
Getting the error and a crash today with Haruna video player. - But yeah, the crash seems unrelated. Please ignore.
