This seems to be an issue buried in Python Paramiko and they way it is  
packaged for openSUSE. PyHoca-GUI relies on a working Paramiko Python  
module. What it does above is

  paramiko.RSAKey.generate(RSAKEY_STRENGTH)

And this call somehow fails. Please get this fixed for your distro and  
then pyhoca-gui will (hopefully) work.
