Thats not "grind to halt" really, but ok. What do you have built?
It seems to load a libgvfsdbus.so, so gvfs seems to be there, but with
no gconf module? Do you have a session dbus running?

If you have gvfs installed but not with gconf what should happen is that
the query_info on the uri should sniff the mimetype and launch app
depending on that.

Does gvfs stuff work at all in your installation? For instance, what
does "gvfs-info http://gretl.sourceforge.net"; print? for me it does:

gvfs-info http://gretl.sourceforge.net
display name: /
edit name: /
type: unknown
size: 14276
attributes:
  etag::value: "37c4-467d4ae02f640"
  standard::display-name: /
  standard::edit-name: /
  standard::content-type: text/html
  standard::size: 14276
  id::filesystem: type=http,uri=http%3A%2F%2Fgretl.sourceforge.net,__mount_prefix=%2F
  time::modified: 1240063057
  time::modified-usec: 0

which should lanuch whatever app is registered for text/html.
