I suspect the underlying problem is that he wasy trying to print while
the capture was still running - "cf->unfiltered_count" is set by:

	"read_cap_file()" - but that's not used in an "Update in real
	time" capture;

	"colorize_packets()" - but he probably hadn't run any
	colorization or display filtering.

This appears to be "fixed" in the current CVS tree because the "Print"
menu option isn't enabled while the capture is in progress; however, I
see no reason to forbid printing packets, so that's really a misfeature.

I'll look into this.
