Subject: Bug#1153: x2goruncommand must stop exporting LD_LIBRARY_PATH with nx-libs 3.6.x

Package: x2goserver
Severity: important
Version: 4.1.0.0
Control: tags -1 patch

In Arctica's nx-libs, we changed the path where the libX11.so symlinks  
to libNX_X11.so reside.

This makes applications in X2Go behave strange esp. Actually, the  
LD_LIBRARY_PATH setup is for nx-libs 3.5.0.x and obsolete in 3.6.x.

Here is a simple patch that stops setting LD_LIBRARY_PATH, if nx-libs  
3.6.x is installed:

```

  if [ "$sndsys" == "esd" ]; then
         export ESPEAKER="localhost:$4"

```

Thanks to Orion, who brought this up.
