[Bug 1627564] Re: Debconf crash due to assertion failure in ensure_surface_for_gicon [gtkiconhelper.c:493] (when png loader is missing/during upgrades)
> OTOH I think there is an easy fix for GTK+ to always include an
"image-missing" icon at compile time
I'm sorry, it's not that easy. A PNG icon is indeed included, and it
gets found properly (also from the actual icon theme; that is a
dependency of GTK). The problem is the ability to load PNGs *at all* is
not available sometimes during the middle of dist-upgrades.
I think extending that test program in Debconf (referred to in the IRC
log above) to do a bit more work - trying to load an icon - might make
the fallback trigger in this case too.
e.g:
my $window = Gtk3::Window->new('toplevel');
my $icontheme = Gtk3::IconTheme::get_default;
my $icon = $icontheme->load_icon('image-missing', 32, []);
If you manually remove '/usr/lib/*/gdk-pixbuf-2.0/2.10.0/loaders.cache'
(suggest doing this in a VM) then you can reproduce this by extracting
the program out of Debconf.

Going to reassigning to debconf, while it's gtk not handling when loaders are not configured that's during-update issue where the system is in inconsistent state and I'm unsure GTK itself is where to fix the problem it had been discussed a bit on https://irclogs.ubuntu.com/2020/04/21 /%23ubuntu-release.html#t16:15 debconf handles GTK failing, but that's not a clear failure case, the error is hit when trying to load icons ... one way to address this would perhaps be to make debconf try to do that and fallback as well if it's failing. Reassigning to foundation and tagging rls-ff-incoming since that's a common case of upgrade failure ** Package changed: gtk+3.0 (Ubuntu) => ubuntu ** Tags added: rls-ff-incoming -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1627564 Title: Debconf crash due to assertion failure in ensure_surface_for_gicon [gtkiconhelper.c:493] (when png loader is missing/during upgrades) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1627564/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
