I am one of the debian nginx maintainers. Is it possible to provide a
patch for nginx-1.2 series since the relevant commit is not backportable
Debian stable (wheezy) comes with nginx 1.2 and unfortunately only
security fixes are allowed.
Ubuntu might have a similar problem, although I have not checked the
applicability of the patch there (Ubuntu comes with nginx-1.4).
