Yes!

OK...

Install with ;;apt-get install <package>=<version>'', version numbers  
of packages are shown when using ,,apt-cache show <package>''

You want the ones we built, they start with 2:3.5.0 in the version number.

Yeah, this sounds weird... Please check your apt sources again, our  
packages files are clean, I have checked that. You seem to be pulling  
in packages from

deb http://packages.x2go.org/debian lenny main

I would try this:

Purge everything NX'ish, X2Go'ish...
Install NX packages from packages.x2go.org squeeze heuler
Install FreeNX from Launchpad (lucid)
Install the rest of X2Go from packages.x2go.org squeeze main (or heuler)

Greets,
