Description of problem:
In some cases, tracepath continues tracing although it has already reached the intended destination host. For example:

[vaj4088@coyote ~]$ tracepath 24.221.130.104
 1: 192.168.0.241 (192.168.0.241) 0.314ms pmtu 1500
 1: firewall (192.168.0.250) 0.578ms
 2: 10.253.1.1 (10.253.1.1) asymm 3 84.814ms
 3: aztutmrt01.az.sprintbbd.net (24.221.129.1) asymm 2 93.968ms
 4: <deleted> (24.221.130.104) asymm 5 162.687ms

     Too many hops: pmtu 1500
     Resume: pmtu 1500
[vaj4088@coyote ~]$

tracepath should have stopped at the line labeled "4:", but continued on.

<deleted> is a name from my /etc/hosts file that has been deleted to protect the name of an innocent bystander.

Version-Release number of selected component (if applicable):
iputils-20020927-22

How reproducible:
Always

Steps to Reproduce:
My example shows how I reproduce the problem. Networks being what they are, I don't know how to reproduce it in your circumstances.

Actual Results: See description.

Expected Results: Should have looked something like:

[vaj4088@coyote ~]$ tracepath 24.221.130.104
 1: 192.168.0.241 (192.168.0.241) 0.314ms pmtu 1500
 1: firewall (192.168.0.250) 0.578ms
 2: 10.253.1.1 (10.253.1.1) asymm 3 84.814ms
 3: aztutmrt01.az.sprintbbd.net (24.221.129.1) asymm 2 93.968ms
 4: <deleted> (24.221.130.104) asymm 5 162.687ms
     Resume: pmtu 1500 hops 4 back 3
[vaj4088@coyote ~]$

Additional info:

Note that the following works fine:

[vaj4088@coyote ~]$ tracepath 24.221.129.1
 1: 192.168.0.241 (192.168.0.241) 0.342ms pmtu 1500
 1: firewall (192.168.0.250) 0.581ms
 2: 10.253.1.1 (10.253.1.1) asymm 3 121.557ms
 3: aztutmrt01.az.sprintbbd.net (24.221.129.1) asymm 2 223.267ms reached
     Resume: pmtu 1500 hops 3 back 2
