This was a month ago, and there wasn't any response, so I guess there's little chance that there'll be any development in this bug report, so I'm closing it. If progress can be made, please respond to the debbugs address and we'll reopen. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
