Comment (by nejucomo):

 I just verified that the same 1.9.1 gateway described above *now* has the
 behavior described for the 1.8.3 gateway.  Specifically:

 {{{
 $ curl
 'http://127.0.0.1:3456/uri/URI:DIR2-RO:7qyqs2kopmglnstoquia4stxta:iz5jmy5cq34spq5h47my55mmb4uucfolbnfb6lxxe545su26cgta/?t=json'
 [
  "dirnode",
  {
   "mutable": true,
   "verify_uri":
 "URI:DIR2-Verifier:l6onu7huqqij624tbj2sbbuyve:iz5jmy5cq34spq5h47my55mmb4uucfolbnfb6lxxe545su26cgta",
   "ro_uri":
 "URI:DIR2-RO:7qyqs2kopmglnstoquia4stxta:iz5jmy5cq34spq5h47my55mmb4uucfolbnfb6lxxe545su26cgta",
   "children": {
    "helloworld.txt": [
     "filenode",
     {
      "mutable": false,
      "format": "CHK",
      "ro_uri": "URI:LIT:jbswy3dpeblw64tmmqqqu",
      "metadata": {
       "tahoe": {
        "linkmotime": 1327402892.605141,
        "linkcrtime": 1327402892.605141
       }
      },
      "size": 13
     }
    ],
    "index.html": [
     "filenode",
     {
      "format": "CHK",
      "verify_uri": "URI:CHK-
 Verifier:cmszlggyh6ljvy4kzfqdfbdtx4:5a6alvxpu2vsw45aiqfjriukxaoxno4har2hz2s2isczyppkuhja:1:1:647",
      "ro_uri":

       }
      }
     }
    ]
   }
  }
 ]
 }}}

 -and now when requesting the "index.html" cap directly:

 {{{
 $ curl
 'http://127.0.0.1:3456/uri/URI:CHK:kqnb2i6tufbyrou4klft7qn36y:5a6alvxpu2vsw45aiqfjriukxaoxno4har2hz2s2isczyppkuhja:1:1:647'
 NoSharesError: no shares could be found. Zero shares usually indicates a
 corrupt URI, or that no servers were connected, but it might also indicate
 severe corruption. You should perform a filecheck on this object to learn
 more.

 The full error message is:
 no shares (need 1). Last failure: None
 }}}

 I can verify the version with:

 {{{
 $ curl 'http://127.0.0.1:3456/' | grep 'My versions'
