[tex-k] Problems for HOME with trailing "/"

not sure whether this is a full-grown bug or just a difficult to find 
annoyance.  A more formal description:

The problem:
kpsewhich (probably other kpathsea tools as well) are incredibly slow when 
called with ${HOME} having a trailing slash.  Calling e.g. xdvi took ~80 secs 
on this AMD X2 machine.  Executing "HOME=/home/<NAME> xdvi" resulted in 
normal speed.

My output from kpsewhich --version :
kpathsea version 3.5.5

I found this older mail with a similar problem:

If this cannot be fixed (maybe by parsing ${HOME} to remove any trailing 
slashes before applying it to other variables?) I would like to see a new 
item in http://www.tug.org/texinfohtml/kpathsea.html#Slow-path-searching 
noting about this problem, like so:
  * You are recursively searching your home directory.  This may happen 
inadvertedly when your ${HOME} environment variable ends with a slash ('/').  
Under Linux this can be changed by the system administrator in /etc/passwd.
