Thanks for your response. Yes, I think #1127710 is the same issue I am seeing. As you said there, I expect it is related to this gdk-pixbuf transition. I agree that you designate #1127710 as blocking #1127158. To answer your questions to the OP of #1127710: About firefox on my box, it is not affected and still works. I don't use Loupe. I also noticed a report that evince seems affected by this transition and I don't know yet if evince works on my box either because I don't use it. I also verified the Thunderbird bug exists on my box with Intel integrated graphics and Raptor Lake CPU on the bare metal, and in both KVM/Qemu and Xen/Qemu virtual environments, and in all cases the bug appears when launching Thunderbird in Gnome. Reboot does not help. As I mentioned in another message to #1127158, I can workaround this bug in current sid by running Thunderbird under LXQt, presumably because the gdk-pixbuf transition does not have as many adverse affects on environments based on Qt instead of GTK. I have not tested other DEs such as KDE Plasma and XFCE. I would expect XFCE would be more likely to be affected than KDE Plasma because, like Gnome, it uses GTK. I do have some skills to try to identify a cause of this bug, but unfortunately not lots of time and I think it may take some time, but I think there is plenty of time before Forky is released. Until instructed otherwise, I will send further reports about this Thunderbird crash I am seeing to #1127710, per your request. Cheers.
