So far I have been unable to reproduce the problem on anything earlier than revision 13346. I will keep advancing till I can find what change broke it for me.

OK, I have tested this on three different linux systems with the latest svn and I get the same thing on all of them. 

Each was run with configure --disable-ethereal

Not sure if that could be causing some problems or not.
For some reason the optarg is null.
I will check it out futher after lunch.
