Comment # 6 on bug 1170461 from Matthias Gerstner

Can you please test the patch in attachment 836960 [details]? Apply like this:

```
root # cd /
root # patch -p 1 </path/to/stf.diff
```

It should fix the error. However, the reason for the error is that some
iptables line with --sport 138 appears that the conversion tool can't correctly
deal with. This patch now simply skips over such entries. This also means that
the migration will be incomplete. But it probably is incomplete anyways ... you
will need to inspect the outcome and adjust as necessary.
