travis complains:
```
AssertionError: Line matched when shouldn't have: /home/travis/build/fail2ban/fail2ban/fail2ban/tests/files/logs/stunnel:2 '2011.11.21 14:29:16 LOG3[28228:140093368055552]: SSL_accept from 10.7.41.61:33454 : 140890C7: error:140890C7:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:peer did not return a certificate\n'
```

should be ```match``` not ```matches```?
