Hello, There was also a bug in at-spi2-atk, I have uploaded a fixed package.
So, to summarize the needed steps to get d-i accessible from debian live: - at-spi2-atk fix (debian/patches/p2p), done. - adding a udeb for libgail-common & libgail18, filed as #816720 - setting GTK_MODULES=gail:atk-bridge in the debian-installer.sh script, filed as #816705 - adding the content of libgail-common-udeb and libatk-adaptor-udeb to the d-i image used by the live installer. I don't know which image the live installer uses, is it just using the standard gtk d-i image (in which case we can just add the packages to g-i), or is it building its own image? Samuel
