Summary 0004557: iftop displays zeroes for all values
Description Following an upgrade to the current or unstable branches, iftop stops working and displays only zeroes:

TX: cumm: 0B peak: 0b rates: 0b 0b 0b
RX: 0B 0b 0b 0b 0b
TOTAL: 0B 0b 0b 0b 0b

Switching back to the stable branch, and reinstalling only iftop and libpcap, it works again.

I have the same problem. Solved it by reverting libpcap from unstable branch. Seems libpcap is the culprit.

Still does not work. Only zeroes are shown regardless of the traffic.

I have verified the problem with newly build 0.17 and 1.0pre2, both don't show any traffic with libpcap 1.1.1, but do show with 0.9.7. I'll get in contact with Paul.

After upgrading to 1.0pre4, I observe the following behaviour:
  it works on my yukonx interface
  it does not work on the rge interface.

So it probably is an incompatibility with some drivers, maybe introduced at some point in S10 or libpcap. At this point, I think closing the bug is the best way forward.
