This is an apache bug.
Use a newer apache version:
Generic steps to install a newer version of a package with apt than provided in the stable stream:
In /etc/apt/apt.conf.d add the following file
99defaultrelease:
APT::Default-Release "stable";
In /etc/apt/sources.list.d – add urls for testing / unstable sources
stable.list:
deb http://ftp.de.debian.org/debian/ stable main contrib non-free deb-src http://ftp.de.debian.org/debian/ stable main contrib non-free deb http://security.debian.org/ stable/updates main contrib non-free
testing.list:
deb http://ftp.de.debian.org/debian/ testing main contrib non-free deb-src http://ftp.de.debian.org/debian/ testing main contrib non-free deb http://security.debian.org/ testing/updates main contrib non-free run
apt-get update
and then install what you need with
apt-get -t testing install something
So for our purpose:
apt-get update apt-get -t testing install apache2 service apache2 restart
Choose to keep all your default config files with no changes.
