 I have found that when my client (running 1.9.0.post131) connects to my
 introducer (also running 1.9.0.post131), I can load the introducer status
 page fine. Within a few seconds (probably once other clients connect) the
 status page will fail to load.

 The following is in twistd.log:

 FWIW, all of the other clients are running 1.8.3. Also, this is on the
 I2P-hosted volunteer grid.
