according to http://www.debian.org/Bugs/Developer.en.html, grave means "makes the package in question unusable or mostly so, or causes data loss, or introduces a security hole allowing access to the accounts of users who use the package."
I don't think this applies to this bug. Considering this bug is holding nvidia drivers out of sarge, I think this bug should really be downgraded! Please reconsider this bug severity soon. -- regards, Reinhard -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
