Basically the same problem occurs at a place where debhelper would want to call dpkg-parsechangelog.
Maybe a good solution would be not to redirect stderr to /dev/null; this way, all messages would be clearly visible, and I think they wouldn't print anything to stderr in normal course of operation anyway. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
