x2goclient crashing

Hi,

I have a "little" problem.
I built x2goclient, the nx-libs and x2goserver from the SOURCES and it 
does work, when client and server are running on the same computer.
But x2goclient crashes, as soon as it runs on a different one, after 
showing a popup window, telling me the server reset the connection.

Is there any one having an idea, why that is the case?

See the client's debug messages here: http://pastebin.com/RTRhRwaZ
and the server's log output here: http://pastebin.com/qzEUjkyK

Thanks,
Oliver
