 Grr.  My blog broke.
 [http://testgrid.allmydata.org:3567/uri/URI:DIR2-RO:j74uhg25nwdpjpacl6rkat2yhm:kav7ijeft5h7r7rxdp5bgtlt3viv32yabqajkrdykozia5544jqa/wiki.html
 My blog] is hosted on the Test Grid.  That was really the last straw!  I
 don't mind if everyone else who uses the Test Grid is inconvenienced by it
 being impossible to create directories, but I'm not going to leave my blog
 broken!  So I upgraded the web gateway from:

 {{{
 allmydata-tahoe: 1.4.1-r3897, foolscap: 0.4.1, pycryptopp: 0.5.2-1, zfec:
 1.4.0-4, Twisted: 2.5.0, Nevow: 0.9.18, zope.interface: 3.3.1, python:
 2.5.2, platform: Linux-Ubuntu_8.04-i686-32bit, simplejson: 1.7.3,
 argparse: 0.8.0, pyOpenSSL: 0.6, pyutil: 1.3.16-12, setuptools: 0.6c12dev
 }}}

 {{{
 allmydata-tahoe: 1.4.1-r3995, foolscap: 0.4.1, pycryptopp: 0.5.15, zfec:
 1.4.0-4, Twisted: 2.5.0, Nevow: 0.9.18, zope.interface: 3.3.1, python:
 2.5.2, platform: Linux-Ubuntu_8.04-i686-32bit, sqlite: 3.4.2, simplejson:
 1.7.3, argparse: 0.8.0, pyOpenSSL: 0.6, pyutil: 1.3.16-12, setuptools:
 0.6c12dev, pysqlite: 2.3.2
 }}}

 Now instead of {{{Connected to 350  of 61 known storage servers}}} it says
 {{{Connected to 14 of 24 known storage servers}}} and my blog works
 nicely.  Also, people can create directories again.

 This doesn't mean that this issue is resolved for v1.5 release though.  We
 still need to investigate.
