I just tried to use the newest libav possible. I downloaded
"libav-11.3.tar.gz" and compiled from sources. Unfortunately, the configure
script does not accept "--enable-libxcb", so I compiled it using only
"./configure --enable-x11grab --enable-gpl". I also compiled the newest
x2goserver (x2goserver-4.0.1.19.tar.gz) using the default options.

Now, the output is almost the same as previously (the only difference is
the version of the library):

login at baga:~$ avconv -f x11grab -r 25 -s 1600x900 -i :50 -vcodec libx264
-threads 4 output.avi
avconv version 11.3, Copyright (c) 2000-2014 the Libav developers
  built on Mar 24 2015 17:29:51 with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)
[x11grab @ 0x22eb260] device: :50 -> display: :50 x: 0 y: 0 width: 1600
height: 900
[x11grab @ 0x22eb260] shared memory extension  found
Segmentation fault (core dumped)

Any idea what is happening?
