Control: reopen 766884

Let's reopen #766884 for tracking, it's not really fixed, but just
avoided. Unfortunately #781232 is opened. I would like to block this
version to testing as it's not the proper way of fixing the problem
(but it is indeed the most straightforward way of avoiding it).

Maintenance status of libxml2 upstream is a little bit complicated
because the code base tend to have quite some issues that can easily
trigger new bugs, so that fix for one particular bug may lead to
another new one. Reverting to older version isn't a solution because I
believe not all of the memory related fixes can be ignored even for
the case of security, that's the reason why I tend to carry quite a
lot of patches for stable releases.

The proper way of working this bug around would be bisecting and
patching which is quite time consuming. I haven't yet managed to get
it done and help is welcomed, but if no one step up I'll do it
eventually (or cross finger for finding a proper fix, :D).
