Title:
  Vinagre closes connection to tightvncserver 2.0 beta4 immediately

Status in “gtk-vnc” package in Ubuntu:
  In Progress
Status in “gtk-vnc” source package in Lucid:
  New

Bug description:
  ===============================
  SRU Justification:
  1. Impact: vinagre fails to connect to tightvncserver
  2. How bug was addressed: a one-line (one-character) fix was pulled from upstream which fixes the initial protocol greeting to include a newline (it was a NULL)
  3. Minimal patch: see attached gtk-vnc.debdiff
  4. TEST CASE: start tightvncserver, then try to connect to it with vinagre
  5. Regression potential: It could break connections from/to other vnc clients/servers.  Connections should be tested between all, including 'kvm -vnc'. 

  Binary package hint: vinagre

  Ubuntu 10.04 (Lucid), Vinagre 2.30.2-0ubuntu1
  When I connect to a TightVNC-Server 2.0 beta4 the conntection closes immediately with
  "Connection to host <ip> was closed."
  Other VNC-Viewers are working without a problem.

  SRU Justification:
  Bug prevents gtk-vnc based clients from working with upcoming tightvncserver releases.

  Risk of regression:
  Low, patch is a one-line change from upstream only affecting the version string sent in response to the server.

  Testcase:
  1) Install tightvncserver v2 (not yet in Ubuntu or Debian repositories, alas)
  2) start tightvncserver session
  3) connect to it with vinagre or another gtk-vnc client; client should attach successfully.
