Title:
  gvfsd-http loops requesting the same page

Status in “gvfs” package in Ubuntu:
  Confirmed

Bug description:
  Seen on a lucid system:

  # pgrep -fl gvfs

  Until I attached gvfsd-http with the debugger, it was bombarding a web
  server with HTTP HEAD requests for the same URL at about 6 seconds'
  interval. (The web server responded in less than a second.) The
  requests were all using the same TCP connection, except when the
  server returned 503 Service Unavailable; then a new TCP connection was
  established and used.

  Here is the backtrace from gdb:
