Does this it help? I can find a program call "bt", I am running on a Ubuntu machine and I am just a little bit more than a basic linux user.

We can’t really do anything with that without a C backtrace (though I suppose we could research what NXclient is and try to reproduce it); could you attempt the same thing within GDB, and send us the C backtrace (type bt once the program has crashed) ? -- ¿Dónde estará ahora mi sobrino Yoghurtu Nghe, que tuvo que huir precipitadamente de la aldea por culpa de la escasez de rinocerontes?
