clock jump during i2p start results in router hanging on "Network: Testing"

[anonym]

Steps to reproduce:
1. Start a i2p (I use KYTV's packages from his/her PPA, on Debian squeeze)
2. Wait a few seconds, then set the clock back 2 hours or so.

Result:
According to the router console, the router is stuck on "Network: Testing", and indeed I'm never able to use the I2P network. The HTTP proxy and other client tunnels never starts to listen on any ports according to netstat.

The following is from log-router-0.txt (complete file is also attached):
