I have two servers running fail2ban, one version 0.8.3 and the other 0.8.4. Both servers frequently log fail2ban.actions.action: ERROR's when fail2ban is restarted. The errors occur with various jails, sometimes when starting but mostly when stopping the jails. See the attached file for snippets from both log files.

def __processCmd(self, cmd, showRet = True):
beautifier = Beautifier()
for c in cmd:
This change seems to have fixed the errors on both servers. I haven't seen this problem reported here, so I'm reporting it on behalf of Cyril Levert and Soldat Ryan.
