This is a minor issue.

A user of my program ran into a Linux issue on Fedora 39 that I don't know how to resolve.

I compile my application on Rocky Linux 8.9.1 and distribute most (non-system) libraries with it, including libpango and libpango-cairo, based on what ldd reports as dependencies (recursively).

My application works fine on RL8.9.1 and Ubuntu 22.04.3 LTS, after doing:

sudo apt reinstall libgdk-pixbuf2.0-0

But, my user reported a crash on Fedora 39 when accessing the Native File Chooser, instead of my custom file chooser.  He gets the following warnings and error:

Gtk-Message: 23:19:51.272: Failed to load module "xapp-gtk3-module"

(mrv2:7991): Gtk-WARNING **: 23:19:51.318: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.

Gtk:ERROR:gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Adwaita/scalable/status/image-missing.svg: Unable to load image-loading module: /usr/lib64/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.so: /usr/lib64/librsvg-2.so.2: undefined symbol: pango_context_set_round_glyph_positions (gdk-pixbuf-error-quark, 5)

To be honest, I am not too familiar with how the Native File Chooser works as I never use it.  Neither libpixbufloader-svg.so, librsvg-2.so nor libgvfscommon.so show as dependencies of either my executable nor the libpango libraries, so I am a tad lost.  I don't distribute neither libpixbufloader-svg nor librsvg-2.

Anybody has ideas?
