** Description changed:

  [Impact]
  
  The tkblt package lacks the definitions that come in the `graph.tcl`
  file:
  
      % package require tkblt
      3.2
      % blt::RemoveBindTag
      invalid command name "blt::RemoveBindTag"
  
  This affects the saods9 package: When one selects the "Analysis -> Line
  plot tool" menu item, an error message pops up with
  
  An internal error has been detected. invalid command name
  "blt::RemoveBindTag"
  
  and the following graph is empty.
  
  Similar error messages come up in several places, significantly
  decreasing the usability of saods9.
  
  The problem is fixed in the Debian version 3.2.8-1. I will provide a
  backport for Ubuntu.
  
  [Test Case]
  
  1. install tkblt, and then run the "wish" Tcl shell. With the bug, it
  will present the output shown above.
  
  2. install saods9, start "ds9", open the "Analysis" menu and select
  "Line Plotting tool...". With the bug, an error message will appear.
  
  [Regression Potential]
  
  saods9 (and tksao, which is also in the saods9 source package) is the
  only reverse dependency of tkblt (in fact, upstream made tkblt an split-
  off from saods9), and saods9 is tested with the fix. Also, the fix is
  quite straightforward; so no regression is expected. In the worst case
  (if the fix would be completely wrong), it would make saods9 unusable.
