byobu-config does not run

[Søren Holm]

Running byobu-confi gives me this output.

$ byobu-config
Traceback (most recent call last):
  File "/usr/bin/byobu-config", line 32, in <module>
    import snack
  File "/usr/lib/python2.7/dist-packages/snack.py", line 44, in <module>
    import _snack
ImportError: /usr/lib/python2.7/dist-packages/_snack.so: undefined symbol: _Py_RefTotal

It is impossible to configure byobu without it.
