Cups eat all my cpu on admin "Add printer"

[Laurent Hug�]

Hi,

I've got a big problem in configuring cups. I launch cupsd, log in http://127.0.0.1:631/admin, I enter the root's password and select "Add printer" ; then cups takes more than three minutes at 98% load (source : top with an AMD Athlon XP 2400+) before displaying the page ; I fill the fields, validate, and it turns again at 98% load for three minutes to display the page with port ; and then nothing because there's no port available on the menu !
The behaviour of my browser (Konqueror) is strange : begining at 1ko/s, then rapidly to 500o/s, 250o/s, then nothing. My firewall doesn't filter anything on localhost.
I can't find anything special in the log, except lines of things like :
        Closing client 8 after 300 seconds of inactivity...
        CloseClient() 8
        CloseClient: Removing fd 8 from InputSet and OutputSet...
        ReadClient() 6, used=0
        CloseClient() 6
        CloseClient: Removing fd 6 from InputSet and OutputSet...
        DeleteCert: removing certificate for pid 0
        AddCert: adding certificate for pid 0
        PID 1591 exited with no errors.
        DeleteCert: removing certificate for pid 1591
        WriteClient() 5 1253 bytes
        REQUEST localhost - root "GET /admin/?op=add-printer HTTP/1.1" 200
2477
	...

Here is my cupsd.conf :
	root$ grep -v "^$\|^#" /etc/cups/cupsd.conf	(to avoid all comments)
	AccessLog syslog
	DataDir /usr/share/cups
	DocumentRoot /usr//share/doc/cups
	ErrorLog syslog
	FontPath /usr/share/cups/fonts
	LogLevel debug2
	PageLog syslog
	RequestRoot /var/spool/cups
	ServerBin /usr/lib/cups
	ServerRoot /etc/cups
	TempDir /var/spool/cups/tmp
	Port 631
	Browsing Off
	<Location />
		Order Deny,Allow
		Deny From All
		Allow From 127.0.0.1
	</Location>
	<Location /admin>
		AuthType None
		AuthClass System
		Order Deny,Allow
		Deny From All
		Allow From 127.0.0.1
	</Location>

I've remade cups with no optimization, I've checked every directory specified in cupsd.conf, I've checked everything with lpinfo and cups-config, I've tried to use another browser (lynx), I've commented the lines Order Deny,Allow Deny From All Allow From 127.0.0.1 in <Location /admin>, but there's no evolution.

Is somebody able to help me ?
