[X2go-Dev] NX (redistributed) -- x2goagent fully integrated into NX-libs (call for testing)

the deb-urls are
# FreeNX
deb http://ppa.launchpad.net/freenx-team/ppa/ubuntu lucid main
# X2Go
deb http://ppa.launchpad.net/x2go/stable/ubuntu lucid main

the versions now running are:
x2goagent 3.5.0.5-0~72~lucid1
x2gognomebindings 2.0.1.3-0~47~lucid1
x2goserver 3.0.99.7
nx-common 0.3.1+svn59-0~ppa1~lucid1
nxagent 1:3.5.0-1-2-0ubuntu1ppa8
nxauth 2:3.5.0.2-0~135~lucid1
nxclient 3.4.0-7
nxlibs 1:3.5.0-1-2-0ubuntu1ppa8
nxproxy		2:3.5.0.2-0~135~lucid1
neatx-server                0.3.1+svn59-0~ppa1~lucid1
libnx-x11                   2:3.5.0.2-0~135~lucid1
libxcomp3                   2:3.5.0.2-0~135~lucid1
libxcompext3                2:3.5.0.2-0~135~lucid1
libxcomp3                   2:3.5.0.2-0~135~lucid1
libssh-4                    0.4.8-2

and pyhoca-gui and the corresponding python-libs,  but i think this
isn't relevant here.

i only tried connecting to the server via nxclient 3.4 or 3.5 from
ubuntu-machines (if this is relevant, but i think not).

I pinned the x2goserver-package to 3.0.99.7 (and patched some things
manually) because of some problems with the newer ones, so yes, i have
old code.. but i did not recognised that this bug was fixed, sorry. For
the "problems" i had with newer x2goserver-packages and my patches: when
i have more time, i will look if there are gone and, if not provide, the
necessary information and/or patches. The problem above with nxagent
should not be affected by theses differences.
