ntop does not collect data

From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-12smp i686) Description of problem: ntop does not collect any data. How reproducible: Always Steps to Reproduce: 1.run ntop (/etc/init.d/ntop start) 2.go to http://localhost:3000 3.Click on "IP traffic" and then chose any of L-L, L-R Actual Results: You will see "No data collected yet" (though program was runnig for few days) Expected Results: Matrix of traffic between hosts on the subnet Additional info: This error is reported on ntop.org and suggested solution is that: "RedHat has broken libpcap, get a prestine source and recompile against it". I have not done it since I do not believe that RedHat would ship a broken libpcap :)
It appears that it does collect some data, e.g. "Data Rcvd" top menu shows some data (on all sidebar selections: "All Protocols", "IP" etc..). "Data Sent" works as well. For "IP Traffic" only "Local Usage" and "L->R" shows something. "Matrix", "L<->L", "R->L" do not show any data ("No Data To Display (yet)").
On a fully updated RHL 6.2 (using up2date today) gtop does not collect any data either.
further to my previous comment: rebuilding libpcap-0.6.2-7.i386.rpm and ntop-1.3.1-1.i386.rpm from source seems to solve the problem.
update libpcap-0.6.2-7 in rawhide should fix this problem
