there is already
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=702711
which has a patch for eatmydata that I can confirm to fix the issue.
Also, it seems to be an issue on sid only (wheezy is fine), so I guess
the new opencv triggered the actual ctor bug in eatmydata as described
by Roland.
To fix this temporarily for a mini-buildd sid distribution, rebuild
eatmydata with the patch, and use something like
"apt-get install eatmmydata/sid-test-unstable"
in the chroot setup script.
Hth!
