Bug description:php-fpm SIGSEV running friendica on nginx

Description:
------------
Hi,

I am running a friendica (friendica.com) instance on a bitfolk.com VPS with
480MB ram. As webserver I'm using nginx. I can cause the site to crash very
easily by clicking around on some links.

I am using an up-to-date version of Debian Wheezy. All packages are
installed from the standard repository.

I have attached a backtrace, which is the same with each crash.

It seems as if the error is linked with the facebook connector from
friendica, as it crashes when I try to load the connector settings, or if I
go to the network page, which contains statuses from all connected sites
including facebook.
https://github.com/friendica/friendica-addons/tree/master/facebook

Thanks in advance for helping find a solution!

Best regards,
Frederik
