--- Comment #1 from michael <reeves...@gmail.com> ---
Looks we the "Qt: Session management error" is an internal session management
errot that does not impact kdiff3 functionally.
Qt is trying to access '/tmp/.ICE-unix' which is being blocked by flatpak
default configuration. See
https://docs.flatpak.org/en/latest/sandbox-permissions.html for more on that.
Allowing access to '/tmp' changes the error but does not remove it completely.
As far as kdiff3 not being able to actually do the comparison that can be
adjusted in my build config. Currently this has been set to allow the home
folder via one of flatpak's fixed presets. Otherwise even that would not be
allowed.
Passing '--filesystem=host' to flatpaks at launch will allow as much access to
most directories. A few restricts are enforced even then hence why the Qt
warning doesn't go away. The full command would be:
flatpak run --filesystem=host org.kde.kdiff3
To set this as default run:
flatpak override --filesystem=host org.kde.kdiff3
Next will do this at build time.
