Wireshark · Ethereal-dev: Re: [Ethereal-dev] Crash in latest svn: tethereal colinfo protocolinfo_init() sigsev11

[Jaime Fournier <ober@xxxxxxxxxx>]

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.
