[Orgmode] Links and file association

[Christoph Herzog]

When in org-mode I try to open a link that contains the path to an 
OpenOffice.org writer file (file suffix *.odt) emacs assumes (correctly) 
 that it is a zip-file (*odt-files are in fact consisting of several 
zipped files) and opens it in a separate buffer saying "Zip-Archive". 
However, this is of course not what I want.
I am aware that this is most probably not an org-mode issue but has 
perhaps either to do with archive-mode or more generally with the way 
emacs is recognizing file-types. I looked at the /etc/mailcap file, but 
it seems ok and on the Desktop things are working for me. It's only with 
emacs that I have this problem (both emacs 22 and  emacs 23.0.91.1 
(i486-pc-linux-gnu, GTK+ Version 2.16.0). I'm using Kubuntu 9.04

I was unable to find a solution, so I'm hoping that someone perhaps 
knows a way to solve this. Thanks a lot.
