> 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.
