On RHEL-10.0 (currently RHEL-10.0-20250320.8) we cannot start a graphical session due to crash of ibus-daemon under Beaker Image Mode setup (example job: https://beaker.engineering.redhat.com/jobs/10845824) This did not occur with custom generated image mode qxl2s we used with Openstack before to mass-test RHEL-10, but could be coincidence (was earlier, trying now). Same on aarch64 jobs (we made the beaker setup for).

This is the coredumpctl info with the detailed backtrace with debug info installed attached
