UPDATE: Problem with traceroute under 5.1A?

I had several people suggest a firewall or routing problem, but that
isn't the case. This box isn't behind a firewall, and it is reaching
the Internet just fine (it is the primary DNS server for ~4000 zones and
they are all fine). This is a bug in traceroute.

Interestingly, I can traceroute via IP, just not name, even though
traceroute is properly looking up the name (the first line of traceroute
output shows that it resolved the name just fine):

$ traceroute 64.58.76.178

I don't speak for anybody but myself - that's enough trouble.
Original message:
I just upgraded one system here from 4.0F to 5.1A (did a clean install).
I just noticed that traceroute no longer works.  For example, I get:
$ traceroute www.yahoo.com
traceroute to www.yahoo.akadns.net (64.58.76.178): 1-30 hops, 38 byte packets
 1  servers.hsvcore.hiwaay.net (208.147.154.33)  0.976 ms * *
 2  * * *
 3  * * *
<and so on>
When I do the same on another 4.0F system sitting right beside the 5.1A
system (and on the same network), I get:
$ traceroute www.yahoo.com
traceroute to www.yahoo.akadns.net (64.58.76.177), 30 hops max, 40 byte packets

Has anyone else seen this or know of a solution?
