-------------------------------------------------+-------------------------
 The public grid introducer was for a time logging unhandled errors to
 {{{twistd.log}}} that appear to be due to bad connection hints.

 This happened for connections from one IP continuously between 2013-03-01
 18:58:06-0500 and 2013-04-09 18:56:33-0400, and then for a different IP
 for a short time at 2013-05-12 10:54:40-0400. Every two seconds the
 following is logged:

 The same error is also seen by two users in this tahoe-dev thread: [https
 ://tahoe-lafs.org/pipermail/tahoe-dev/2012-December/007893.html]
 (continued at [https://tahoe-lafs.org/pipermail/tahoe-
 dev/2013-January/007913.html]). From that thread, it seems to be due to a
 bug or a misconfiguration that is less obvious than just omitting the port
 in {{{tahoe.cfg}}}.
