I put some debugging statements into some of the gio files, and
here's what I'm getting when I try to open the http reference:

g_io_module_load_module: loaded
  '/opt/gtk2/lib/gio/modules/libgvfsdbus.so'
g_io_module_load_module: loaded
  '/opt/gtk2/lib/gio/modules/libgiofam.so'
g_io_extension_point_lookup: 'gio-local-file-monitor' ->
  gio-local-file-monitor
g_io_extension_point_lookup: 'gio-local-directory-monitor' ->
  gio-local-directory-monitor
g_io_module_load_module: loaded
  '/opt/gtk2/lib/gio/modules/libgioremote-volume-monitor.so'
g_io_extension_point_lookup: 'gio-local-directory-monitor' ->
  gio-local-directory-monitor
g_io_extension_point_lookup: 'gio-local-file-monitor' ->
  gio-local-file-monitor
g_io_extension_point_lookup: 'gio-native-volume-monitor' ->
  gio-native-volume-monitor
g_io_extension_point_lookup: 'gio-vfs' -> gio-vfs
g_io_extension_point_lookup: 'gio-vfs' -> gio-vfs
g_io_extension_point_lookup: 'gio-desktop-app-info-lookup' ->
  gio-desktop-app-info-lookup
g_io_extension_point_lookup: ep = 0x9e92e18
g_file_query_info: iface->query_info = NULL
g_file_query_default_handler gave NULL for
  'http://gretl.sourceforge.net'

And an error message "Operation not supported".
