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'
x2go-INFO-1> "Starting x2goclient..."
x2go-WARNING-1> "Can't load translator: :/x2goclient_he_il"
x2go-WARNING-2> "Can't load translator: :/qt_he_IL"
x2go-INFO-3> "Started x2goclient."

The session I was using is like this:

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