Warn your distributor

My gnucash fix from last night poses an interesting problem - there will be no new gnucash 2.2.x release. So we can fix this potential data loss bug in Debian (probably even in lenny), but what about other distributions? I'm not aware of a formal way to co-ordinate non-security patches like this across distros. (Sure, we can leave it for the vultures on the patch tracker...) Someone should whip up a whizzy web-app, or whatever....
