[bug#73520] [PATCH 0/2] Potential fix for the latest xdg-desktop-portal

[Rodion Goritskov]

Hello!

The problem with the xdg-desktop-portal is due to the configuration changes 
introduced in this commit [1].
Now it relies on using the configuration file to decide which 
xdg-desktop-portal implementation to use. However, as Guix uses 
XDG_DESKTOP_PORTAL_DIR to specify the portal (not the xdg-portal-configuration) 
directory, the newest xdg-desktop-portal skip configuration search at all [2].
If we patch the process of configuration search a little bit - just to continue 
searching in case the XDG_DESKTOP_PORTAL_DIR is specified, but doesn't contain 
any {*}-portals.conf files (our case), we will have the right configuration 
files (at least for KDE I have tested this changes on) to be read by 
xdg-desktop-portal according to priorities (XDG_DATA_DIRS in our case) [3] (so 
they could be even overridden in users' home directory).

It's a bit hacky, but works fine.
