Description of problem:
When installing F44 KDE Plasma from F44 Everything netinst, the installation hangs at the end. Anaconda shows "Configuring gtk3...". I've waited 25 minutes, still stuck. However, in dnf.log I see:

2026-02-23T08:58:40+0000 [3825] INFO RPM callback start %triggerin scriptlet "gtk3-0:3.24.51-3.fc44.x86_64"
2026-02-23T08:58:40+0000 [3825] INFO RPM callback stop %triggerin scriptlet "gtk3-0:3.24.51-3.fc44.x86_64" return code 0
2026-02-23T08:58:40+0000 [3825] INFO RPM callback start %triggerin scriptlet "ibus-0:1.5.34~beta1-2.fc44.x86_64"

So I think this is actually ibus scriptlet running, not gtk3.

During the hang, there's no CPU activity, just this message repeated every 5 seconds in syslog:

09:08:19,535 WARNING brltty:unsupported generic resource identifier: bluetooth:
09:08:24,538 WARNING brltty:unsupported generic resource identifier: bluetooth:
09:08:29,538 WARNING brltty:unsupported generic resource identifier: bluetooth:

09:08:44,532 WARNING brltty:unsupported generic resource identifier: bluetooth:
09:08:49,536 WARNING brltty:unsupported generic resource identifier: bluetooth:

Here are ibus scriptlets:

$ rpm -qp ibus-1.5.34~beta1-2.fc44.x86_64.rpm --scripts
postuninstall scriptlet (using /bin/sh):
if [ "$1" -eq 0 ]; then
  # ibus 1.5.31 has no ibus-xinit and need to delete %_xinputconf here
  # for the back compatiblity for a year.
  /usr/bin/alternatives --remove xinputrc /etc/X11/xinit/xinput.d/ibus.conf || :
  # if alternative was set to manual, reset to auto
  [ -L /etc/alternatives/xinputrc -a "`readlink /etc/alternatives/xinputrc`" = "/etc/X11/xinit/xinput.d/ibus.conf" ] && /usr/bin/alternatives --auto xinputrc || :

  # 'dconf update' sometimes does not update the db...
  dconf update || :
  [ -f /etc/dconf/db/ibus ] && \
      rm /etc/dconf/db/ibus || :
fi
posttrans scriptlet (using /bin/sh):
dconf update || :


I guess it's the posttrans scriptlet running, so this might be a problem in "dconf update || :". But that's just my guess.

Version-Release number of selected component (if applicable):
Fedora-Everything-netinst-x86_64-44-20260222.n.0.iso
anaconda 44.21-1.fc44
gtk3-0:3.24.51-3.fc44.x86_64
ibus-0:1.5.34~beta1-2.fc44.x86_64
dconf-0:0.49.0-5.fc44.x86_64

How reproducible:
always

Steps to Reproduce:
1. run Everything netinst
2. pick KDE Plasma desktop environment
3. see hang at the end during "Configuring gtk3..."
