The fix for kinetic is in https://salsa.debian.org/gnome-team/evince/-/commit/0af145b1 and will be part of the next upload, SRU to 22.04 uploaded now

Hello Sebastien, or anyone else affected,

Accepted evince into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/evince/42.3-0ubuntu2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Hello, Sebastien.
Adding evince 42.3-0ubuntu2 from jammy-proposed does not solve this issue. I am still getting "dbind-WARNING **: [XX:XX:XX.XXX]: Couldn't connect to accessibility bus: Failed to connect to socket /run/user/[UID]/at-spi/bus: Permission denied".

@Tushar, could you share the output for
$ dpkg -l | grep evince?

and do
$ journalctl -f

then start evince and share in the bug what was printed?

@Sebastien, here are the outputs:

$ dpkg -l | grep evince
ii evince 42.3-0ubuntu2 amd64 Document (PostScript, PDF) viewer
ii evince-common 42.3-0ubuntu2 all Document (PostScript, PDF) viewer - common files

$ journalctl -f

and
$ grep at-spi /etc/apparmor.d/usr.bin.evince
?

$ grep at-spi /etc/apparmor.d/usr.bin.evince

  owner /{,var/}run/user/*/at-spi2-*/ rw,
  owner /{,var/}run/user/*/at-spi2-*/** rw,

did you ever edit that file manually? if so the packaging system is going to preserve your version

it seems the file is outdated, could you try to restore to the package version by doing?

$ sudo apt install --reinstall -o Dpkg::Options::="--force-confask,confnew,confmiss" evince

Yes, I edited that file, and that caused the error. Sorry for the inconvenience.

Now, I can confirm that this is a successful fix. Thanks, Sebastien.

Fully patched Ubuntu 22.04, Dec 18, evince 43.3.2 runs fine until a print or print preview is tried on a ps file, resulting in the same error:
$ evince fern.ps
GPL Ghostscript 9.55.0: Unrecoverable error, exit code 1
(libspectre) ghostscript reports: fatal internal error -100
(evince-previewer:13644): dbind-WARNING **: 11:49:59.120: Couldn't connect to accessibility bus: Failed to connect to socket /run/user/1000/at-spi/bus_1: Permission denied

The print icon shows the correct printers, the preview produces a blank window and the error, the Print produces a blank page and the error.

Several ps files tried, resulting in the same error.

No edits of system files were done.

Patches mentioned seem to have been applied successfully.
