Ok, el problema de Jorge es similar o IGUAL al de "julien bodd" 
<julien.lociuro gmail.com>, quien lo solucionó modificando un script 
llamado  /etc/init.d/networking 

Copio acá la solución para el problema de _Jorge_, no confundamos con lo que 
le ocurre a Dani (quien posee un mail que dice "Lourdes" jeje).

Está adjuntado en este mail, el script modificado  /etc/init.d/networking , 
Jorge, tratá de probarlo en tu PC a ver si soluciona tus problemas con 
firefox y KDE... si no lo hace, podrías hace un strace de esos programas?

===========================================================

JULIEN:

I realized that after boot..that I don't have any "lo" interface up! (with 
ifconfig)
Wierd!
I checked the file : /etc/network/interfaces, and it was ok :
> auto lo eth0 
> iface lo inet loopback
> iface eth0 inet dhcp

It seems that /etc/init.d/networking start does not perform well..
After boot..only the eth0 is up.
And sometimes, nothing..In those cases..I was performing a : 
Musix -->Programs -->Knoppix -->Net-->network card configuration.

Then, surprising, again only eth0 were up. Still no loopback.

So I checked the /etc/init.d/networking script..and saw that the restart 
option does not make a ifdown of the loopback.. 
I checked the execution of /etc/init.d/networking restart , and SURPRISING, 
still no loopback after..I suppose that 
Musix -->Programs -->Knoppix -->Net-->network card configuration use that 
script..

 So I executed myself an : ifdown -a and after an ifup -a..
And : WOUHOU..eth0 and loopback are there...
!!! AND ALL APPS ARE WORKING !!!!

Hmmm..for now, I'll put ifdown and ifup in an init script..so I can finally 
play with Musix. 

Do you have any idea for the strange behavior?

Thank you for the strace tip !

Julien.

I don't think it would be a problem to modify the script as I've done.
But, I'm not a linux guru..may be this modification could induce some other 
problems..

The fact is that I checked the /etc/init.d/networking of another debian system 
(agnula) wich I run too..and it is the SAME file ! So, it is not buggous, 
because with agnula I don't have this network problem. 
The problem is coming from somewhere else..but the modification I've made in 
the script just works for me..
If somebody could evaluate the consequences...

I don't know if you saw the modified script. Here it is again : 

For info, the solution I adopted for now is modifying the
/etc/init.d/networking script as so (i just give the changes in comments) :

case "$1" in
start)
        process_options
        log_action_begin_msg "Configuring network interfaces"

        ###### JULIEN'S ADD (ifdown -a) #####
        ifdown -a
        if ifup -a; then
            log_action_end_msg $?
        else
            log_action_end_msg $?
        fi
        ;;

stop)
        if sed -n 's/^[^ ]* \([^ ]*\) \([^ ]*\) .*$/\2/p' /proc/mounts |
                grep -qE '^(nfs[1234]?|smbfs|ncp|ncpfs|coda|cifs)$'; then
            log_warning_msg "not deconfiguring network interfaces: network

shares still mounted."
            exit 0
        fi

        log_action_begin_msg "Deconfiguring network interfaces"
        ##### JULIEN'S REMOVE --exclude=lo #####
#       if ifdown -a --exclude=lo; then

        if ifdown -a; then
            log_action_end_msg $?
        else
            log_action_end_msg $?
        fi
        ;;

force-reload|restart)
        process_options
        log_action_begin_msg "Reconfiguring network interfaces"

        #### JULIEN'S REMOVE --exclude=lo ####
#       ifdown -a --exclude=lo || true
        ifdown -a || true
        if ifup -a --exclude=lo; then
            log_action_end_msg $?
        else
            log_action_end_msg $?

        fi
        ;;
