this was done to work around a critical Ubuntu KDE bug in precise:
https://bugs.launchpad.net/ubuntu/+source/libx11/+bug/985202

The path add-on for Xrandr is only done for KDE sessions. I will be  
happy to revert that nasty hack, but before that, we need someone to  
dig into KDE and (if I recall correctly) the patches applied to  
libxfixes in Ubuntu 12.04 and beyond.

If you disable the LD_LIBRARY_PATH code for Xrandr (x2goruncommand),  
then you will find regularly kwin crashes on KDE in precise+.

Greets,
Mike
