Unable to Change Wallpaper

aandmsantos0910 · August 30, 2025, 2:46am

So I went to change my wallpaper and when I went to choose the wallpaper option in settings the settings window crashed. See below screenshots. After clicking the wallpaper option in settings I get the below from the terminal and the screen closes.

Segmentation fault         (core dumped) systemsettings

I then go to open gwenview which does open but when I go into a folder with pictures in it I get he following output from the terminal and gwenview closes.

sudo pacman -S gwenview libheif qt5-image-formats-plugins kimageformats libkdcraw libmng libpng imagemagick

See if this resolves it

aandmsantos0910 · August 30, 2025, 4:28am

Looks like qt5-image-formats-plugins is not found. But same issue.

Fumikage141 · August 30, 2025, 4:56am

Bump! Gwenview no longer loads any image file for me (I’ve tried jpg, png, webp) and it all results in the same segmentation fault error and close if I attempt to navigate to a folder using the application itself. Package reinstallation also has not worked here.

aandmsantos0910 · August 30, 2025, 5:06am

I also attempted to uninstall and reinstall Gwenview but did not help.

Seems widespread.

There are other posts on other forums and it affects me as well.

aandmsantos0910 · August 30, 2025, 5:26am

Thank you for confirming along with @Fumikage141.

cscs · August 30, 2025, 6:24am

Its exiv2.

You can downgrade that package back if you want.

Fumikage141 · August 30, 2025, 6:55am

Downgraded and now everything’s fixed and working fine, thank you!

aandmsantos0910 · August 30, 2025, 6:57am

What command did you use to downgrade, I am getting the below. Did I do it wrong?

** :$ sudo pacman -U exiv2
[sudo] password for marcs: 
loading packages...
error: 'exiv2': could not find or read package
**

cscs · August 30, 2025, 7:32am

The -U command should be used on a path.

If its still in your cache then somewhere in /var/cache/pacman/pkg.

Or you can use the downgrade package to use the downgrade tool;

sudo downgrade exiv2

aandmsantos0910 · August 30, 2025, 7:43am

Ahh…Yep that did the trick. Thank you for your help!

xircon · August 30, 2025, 8:13am

What is the dodgy package version??

aandmsantos0910 · August 30, 2025, 8:15am

version 0.28.6-1

xircon · August 30, 2025, 8:16am

0.28.6.2 is now available for me, so perhaps it is fixed… Will update brb.

Works:

aandmsantos0910 · August 30, 2025, 8:37am

Thank you for the update. And yes I confirm installed Ver: 28.6-2 is working for me as well.

MrSmartepants · August 30, 2025, 1:56pm

Upgrading exiv2 to v.0.28.6-2 fixed it for me also.

UncleSpellbinder · August 30, 2025, 2:21pm

I just stumbled across this thread while searching for Gwenview issues. Clicking images no longer opened Gwenview. I reinstalled exiv2 and all is well now. Odd. I wonder why a simple reinstall corrected the issue?

Looks like 0.28.6 simply reverted the changes from 0.28.5. 0.28.7-1 just hit the EOS repo and according to the github discussion fixes the original bug and the regression (and some other fixes). https://github.com/Exiv2/exiv2/issues/3376

aandmsantos0910 · August 31, 2025, 1:28pm

I just installed this morning and verified working for me.
