Running x2goclient with a session from the command line, the x2goclient 
window appears and I get a notice about a new SSH key, and as soon as I 
approve it the client crashes. In the console I get this output:

$ x2goclient --debug --session='ogiery remote'

i've installed x2goclient-dbg, but the backtrace on the core file is 
still useless.

I'm not a C/C++ developer so this is difficult to me to investigate that.
