I have been bitten by this bug in my Wheezy box for months, until finally found the fix in Sid/Jessie. So, I've stolen it and it works.
It really deserves a migration into Wheezy to fix the RC bug there. Regards, -- Theppitak Karoonboonyanan http://linux.thai.net/~thep/ -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
