I don't think it's right to reassign this bug to tetex-bin.  That package
may have some related bug (I don't have it installed, so I don't really
know) but the bug described in this report concerns the install-info 
script, which is part of the dpkg package.  

install-info is supposed to be used whenever a package is installed which 
includes documentation in info format.  The purpose of this script is to 
update the "dir file" which contains meta-info about all info files in a 
given info directory.  With the current Debian file system standard, info 
files are stored in /usr/share/info, whereas the buggy install-info script 
updates the dir file in /usr/info (the location of info files in older
releases of Debian.)  Thus, info files are installed in the right location,
but the wrong dir file is updated.  

The effect is that an info reader which just looks in the standard info 
directory, /usr/share/info, will present an incomplete top-level menu.  
On the other hand, an info reader which just looks in the old standard 
location (emacs19 is an example) will present menu items for info files 
which it can't find.
