I tried flow-report now. The result is the same: the decimal number is
shown, not the symbolic name.
This is the only part I'm still missing, the rest seems to work fine.
I could write a short python script that inserts the symbolic name. But I 
think that should be done by flow-report, right?

Here's what I did:
