I guess i can solve this after all, and document it here for other that 
might fall into this hole.
First i was bitten by x2go bug 854

http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=854
or better yet by
https://bugs.launchpad.net/x2go/+bug/1449199

This is fixed by running (on 32 bit servers)
sudo ln -s /usr/lib/i386-linux-gnu/libNX_Xinerama.so.1 
/usr/lib/nx/X11/Xinerama/libXinerama.so.1

The other part was me stomping LD_LIBRARY_PATH.

I think it would definitely be worth mentioning the first item on
http://wiki.x2go.org/doku.php/doc:usage:multi-display.
A heads up on the LD_LIBRARY_PATH wouldn't hurt either.

It might save others time.
This took me a day.
