[SOLVED] All GTK apps relying on gdk-pixbuf2 fail to recognize images.

I'd disagree with you guys, if it's allowed and before you close this, whether OP closed it not that relevant, but that original issue is what all of us are having here, and it's still unresolved.
Help me understand the process (open source hierarchy), maybe I'm missing how this works (we seem to be happy to dismiss this as a glycin, bubblewrap issue), but this isn't some 3rd party package, this is system-wide issue, pixbuf seems to be everywhere. At least, that's what I was trying to emphasize.
Isn't there anything we can do when something like this happens (that's somewhere in the building blocks and original authors don't seem to care enough)?

This is a separate bug with the non-glycin bitmap loader: https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues/271

i fully agree with dragan

"if only they knew what they do."
i know this is sarcastic and inappropriate.

what we can do is to sit and wait!

it would have been better to put all changes into a debian unstable for a quality feedback
without letting arch users be the test dummies for insufficient tested updates.

next check of pkgs there https://bbs.archlinux.org/viewtopic.php … 1#p2264311

It is a mess. It has been hijacked. Regardless, it is serving a purpose and closing it outright would make no sense.
It might make sense to split off everything after post #25 to a new thread. If we don't wrap this up quickly, we may do that.

@dragen, you're more than entitled to an opinion, you're encouraged.
But this thread originates from December 2024, well predating the recent glycin fuss and was down to the OPs flatschpak installation having messed up their $XDG_DATA_DIRS
It is completely unrelated to the problems brought up later except they all affect gdk-pixbuf2 - but some are some earlier threads w/ similar symptoms and yet completely different reasons.

If you're still getting countless stale bwrap processes, there's another (actually two) threads about that and if you experience yet another problem w/ gdk-pixbuf2 (glycin or else) we shall have a thread for this as well.

This is not about wiping problems under a rug but keeping the forum usable now and for posterity.

Well, I had the problem when I upgraded to Gnome 49, and gdk-pixbuf2 was also upgraded, as well as its use of glycin.
What stopped working? Gnome-terminal. Downgrading gdk-pixbuf2 to the latest version that does not use glycin worked.
In my case, I should mention that I have many rules in AppArmor, even for desktop applications, so that was also involved.

I just tried the latest gdk-pixbuf2 update with the latest updates in glycin (version 2.0.2-1). I had previously tried the gdk-pixbuf2 and glycin updates and they failed, but now with glycin 2.0.2.1 it no longer fails.

Downgraded gdk-pixbuf2-2.42.12-1 for the last few days until update of glycin today since when GTK Apps run well again. But when i started a download of a jpg with firejailed Librewolf it crashed:

firejail[110593]: Gtk:ERROR:../gtk/gtk/gtkiconhelper.c:495:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/breeze/status/16/image-missing.svg: No image loaders are configured. You might need to install a package like glycin-loaders.

So I ended up again with downgraded gdk-pixbuf2-2.42.12-1!

One obvious answer is that confining apps from the outside like this with an apparmor profile is doomed to fail.

Better get some popcorn, kick back and watch the show - I for one am curious to understand how the ass-backwards approach of glycin isn't completely bonkers…

With GTK looking more and more like a clusterf*** I'm considering to switch from MATE to LXQt. Sigh.....

~~So I ended up again with downgraded gdk-pixbuf2-2.42.12-1!~~

update: since last updates its not necessary anymore to run GTK Apps like cherrytree, GIMP, w/ downgraded gdk-pixbuf2 and/or glycin, but downloading e.g. an image with a firejailed browser still crashes the latter with the above error. Does anyone know how to deal with that issue of sandboxed apps that failed to call for a loader that in turn is partly sandboxed too (afaik)?
