Bug#1068130: xdg-desktop-portal-gnome cause slow start up time in some application

[Gaston Gonzalez]

Package: xdg-desktop-portal-gnome
Version: 44.2-4
Severity: normal

After upgrading from Bookworm to testing some applications are taking
too long to launch. This happens in applications such as evince, eog,
thunderbird.

The delay comes from a timeout during the program start-up.

For instance, evince seems to timeout in the poll line:

futex(0x55f4aef70878, FUTEX_WAKE_PRIVATE, 1) = 1
eventfd2(0, EFD_CLOEXEC|EFD_NONBLOCK)   = 10
write(7, "\1\0\0\0\0\0\0\0", 8)         = 8
futex(0x55f4aef764f0, FUTEX_WAKE_PRIVATE, 1) = 1
poll([{fd=10, events=POLLIN}], 1, 25000)

Other programs like xpdf or ristretto do not show the same behaviour.

After some digging, it seems that the issue is related to the
applications using xdg-desktop-portal-gnome. After uninstalling it, the
problem is solved.

I am using Debian testing, kernel 6.7.0.
