I've been able to hack together packaging for 1.43.0 (works) and 1.44.0
(hangs when selecting Sinhala), but so much changed between 1.43.0 and
1.44.0 that bisecting between them might not be a very good route.

I've also been able to attach a debugger to debconf. My preliminary finding
is: we enter gtk_container_idle_sizer() in GTK 2 and never exit, because
every time we go into gtk_container_check_resize(), we end up in
gtk_text_layout_emit_changed() which emits a signal that eventually calls
_gtk_container_queue_resize(), so gtk_container_idle_sizer() has more work
to do and we loop indefinitely.

I assume this isn't meant to happen? But please don't mistake me for an
expert on GTK 2, or Pango, or Harfbuzz.

Steps go something like this (is there a better way?):

Host preparation:
- Build interesting libraries (pango1.0, harfbuzz, glib2.0, gtk+2.0) with
  DEB_BUILD_OPTIONS="noopt nostrip nocheck"; we'll need these later

VM preparation:
- Create a new VM booting from virtio disk /dev/vda
- Have an up-to-date bullseye installation on /dev/vda
  (I copied an existing bullseye GNOME installation and upgraded it)
- Make sure a user can log in via ssh and can sudo to root
- Power off the VM
- Attach a CD-ROM device with firmware-bullseye-DI-rc1-amd64-netinst.iso
- Make it boot from CD-ROM
- Boot it
- Start graphical installer
- Proceed with installation, in English, until we get to "Configure the
  network"
- Hit Cancel and Go Back until we get to the menu of installation steps
- Send Ctrl+Alt+F2
- modprobe ext4
- mount /dev/vda1 /mnt
- mount --rbind /dev /mnt/dev
- mount --rbind /proc /mnt/proc
- mount --rbind /sys /mnt/sys
- mkdir /mnt/d-i
- mount --bind / /mnt/d-i
- chroot /mnt bash
  - /etc/init.d/ssh start
  - exit
- ssh in to the chroot'd ssh server; this is our debugging environment
- On the graphical console, send Ctrl+Alt+F5 to go to X11

Debugging loop:
- Use rsync/ssh/cp to get the unstripped libraries into /d-i in the ssh
  session (the root directory of the d-i environment)
- Ctrl+Alt+F2, use udpkg -i to install them in the d-i environment
- In the ssh session, use pstree -p to look at the process hierarchy,
  then kill debconf and everything below it
- Hit Cancel and Go Back until we get to the menu of installation steps
- "Choose language"
- Select Sinhala
- In the ssh session:
    sudo gdb -ex 'set pagination off' \
    -ex 'set sysroot /d-i' \
    -ex 'set logging file /log' \
    -ex 'set logging overwrite off' \
    -ex 'set logging on' \
    /d-i/usr/bin/debconf `pgrep debconf`
- Debug interactively until you get a better idea

Some sample backtraces are attached.

My next step is going to be to try to hack Harfbuzz to disable the Indic
shaper (which is what seems to be in use here) and see whether that stops
the infinite loop. That's unlikely to be an acceptable solution, but it'll
at least tell us whether the Indic shaper is what's triggering this.
