Hi, if http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=681654#52 is correct and the issue is commercial use (and not nondistributability) how about just moving kstars-data-extra-tycho2 to non-free instead of having this bug delay wheezy release? You can always reintroduce it back to main if the issue is solved. -Timo
