Well, that's bizarre.  I can reproduce that problem; I'll have to see
what the cause is.

However, using Tethereal only to convert a capture file is sort of like
using a sledgehammer to swat a fly; you can use editcap instead:

	editcap -F ngwsniffer_1_1 myfile.cap outfile.cap

and, using editcap rather than Tethereal, I *could* read the resulting
Windows Sniffer 1.1 file, so try using editcap instead.
