A fix has been provided upstream. I believe the Ubuntu community should pick up from here and packages the fix.
[ ... snip ...] Darren Tucker: We had some discussion about it amongst ourselves, but we were working on the 8.2 release at the time and we judged it too late to risk including this as it would potentially invalidate testing done to that point. I actually commited[1] this change earlier today, and you can try it yourself by trying either checking out the source or trying a development snapshot[3]. Please let us know if you notice any problems.
