language-support-LANG was still around in 11.04 so the previous change is requiring a dist-upgrade for any user who upgraded from 11.04 to 11.10 and then to 12.04, instead of being limited to machines that were originally installed with 9.04 as was planned. Removing language-support-LANG from the Breaks, which should resolve the issue for these users while still removing language-support-translations on systems. (LP: #1036794)
