addCircuitData lockup

Hoping I've found the right place to ask this.

For several iterations of the alpha client (starting with the first 1.13 I tried) I get intermittent lockups at the following log message during login:
2007-05-24T15:25:32Z INFO: LLCircuit::addCircuitData for 66.150.244.151:12036

It usually takes ctl-z, kill %1, then hunting down the "do-not-run-directly" PID and killing it too. It happens about 1/3 of the times I try to start the client, and rarely twice in a row.

I'm running Kubuntu 7.04 with current NVidia drivers on an FX5200. I've got a wicked-fast ( ~12 mb/s) cable connection, with low latency to that IP above:
10 packets transmitted, 10 received, 0% packet loss, time 8999ms
rtt min/avg/max/mdev = 79.790/83.628/94.323/4.839 ms


The new 1.16_05 client seems to have fixed a bunch of my stability issues, especially in locations with large numbers of people, but this login glitch is killing me. Anyone fight the same battle/won this war?

Thanks.

Actually a better place would probably be to poke around JIRA, the public bug reporting database they have, you log in w. your SL Name & pw.
