BUG: tcpdump keeps running with count=0, fills hard drive

[grantemsley]

I have two pfsense 2.0 systems showing the same behavior.  Both are running pfSense-2.0-BETA1-2g-20100428-0106-nanobsd.img.gz

If I run a packet capture on any interface with count 0 (should be unlimited), tcpdump is never stopped, even after clicking stop from the webUI.  Eventually it will fill the hard drive unless the system is rebooted or you go into the shell and kill it.
