Bug#592693: fv: incorrect path to help files

[Vincent McIntyre <vmcintyr@atnf.csiro.au>]

Package: fv
Version: 3.0-17
Severity: normal


To reproduce:
% fv

select the 'help' item from the main menu

this results in an error message box containing this:
-------------------------------------- start -------------------------------
couldn't open "/usr/lib/fv/doc/deskTopManager.html": no such file or directory
couldn't open "/usr/lib/fv/doc/deskTopManager.html": no such file or directory
    while executing
"error $err"
    (object "::.hyperHelp" method "::iwidgets::Hyperhelp::_readtopic" body line 19)
    invoked from within
"_readtopic $filepath $anchorpart"
    (object "::.hyperHelp" method "::iwidgets::Hyperhelp::showtopic" body line 21)
    invoked from within
".hyperHelp showtopic $topic"
    (procedure "hhelp" line 23)
    invoked from within
"hhelp deskTopManager"
    invoked from within
".fvwinkeeper.menu invoke active"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke active]"
    (procedure "tkMenuInvoke" line 47)
    invoked from within
"tkMenuInvoke .fvwinkeeper.menu 1
"
    (command bound to event)
-------------------------------------- end -------------------------------

The file is actually in /usr/share/doc/fv.
  % ls -l /usr/lib/fv
  drwxr-xr-x 2 root root 4096 2010-08-12 14:24 class/
  -rw-r--r-- 1 root root  482 2000-11-23 02:38 fvInit.tcl

  % ls -l /usr/share/doc/fv/fv/ | grep deskT
  -rw-r--r-- 1 root root  2832 2000-11-23 02:38 deskTopManager.html


The problem appears to be in /usr/lib/fv/fvInit.tcl,

  # Add pathes for help files.
  set env(FV_HELPDIR) [file join "$env(FITSVIEWER_LIBRARY)" doc]

but I'm not sure what the correct patch is, possibly setting FV_HELPDIR
in the /usr/bin/fv wrapper and checking for it being set in fvInit.tcl.
