I supposed the problem was there! I'll look at -listen_tcp and at hosts.allow.
I have doubts about setting hosts. X used to give me errors about not being able to connect (but still worked!). Then I tried to set up hosts correctly and now here's the new "problem".
I've read "man hosts", read the handbook and googled around but it's not very clear what I should write in this file.
My hostname is lucy. It's a laptot that eventually connects to the nearest available network. So it isn't part of a domain or something like that.
In the end I set up the concerned hosts lines to:
::1 localhost localhost.my.domain lucy
127.0.0.1 localhost localhost.my.domain lucy
 
Is it correct?
Why should I leave localhost.my.domain ?

>These messages are errors telling you the window manager cannot manage these mimetypes.  
>Did you remove any ports for handling these types of archive files?

No, I didn't remove anything! But I copied just 3 warnings. There were 130 of them related not only to archive files handling but almost to everything.

I'll try that later!

>When you say "every time you launch a program"  how exactly are you trying to launch a program?  

Either with the kde "launch program", either launching the file in a xterm, either when firefox opens a new popup....And I think those are pretty much all the possible ways I explored!
