bug#57285: xdg-desktop-portal update executables no longer ELF binaries

Hi Guix,

After the recent update to xdg-desktop-portal (commit 
38d7e6d6b7467839c2f577783b6c97194ff5026b), I find that the 
xdg-desktop-portal executalbe is no longer an ELF binary. This causes 
portal using applications (I noticed with obs) to not be able to launch 
the portal, and print messages like "[portals] Error retrieving D-Bus 
proxy: Error calling StartServiceByName for 
org.freedesktop.portal.Desktop: Failed to execute program 
org.freedesktop.portal.Desktop: Exec format error"

Could it be that you have a corrupt (possibly empty) file?  On my
machine I have

1.14.4/libexec/xdg-desktop-portal

Indeed, it was corrupt. After collecting the affected items, and 
re-fetching substitutes, everything looks good.

Thanks!
