svn gives 400 Bad Request error

[Hussam Al-Tayeb]

Hello, I get 400 Bad Request (http://svn.xfce.org) when I try to acess svn.
I tried: svn co http://svn.xfce.org/svn/xfce/modules/trunk xfce4-svn-source
but svn It gives the following error:
svn: REPORT request failed on '/svn/xfce/!svn/bc/19054/modules/trunk' svn: 
REPORT of '/svn/xfce/!svn/bc/19054/modules/trunk': 400 Bad Request 
(http://svn.xfce.org)
Although http://svn.xfce.org works when I open it in firefox.
I have kubuntu 5.10 ( a debian fork )
I can usually use svn fine with kdesvn ond other servers, but I only get this 
error with xfce svn.
Any help is much appreciated.
In the meantime, I'm going to install the 4.2.3.2 grapchical installer 
in /usr/ untill somebody can help with the svn issue.

Thank you,
Hussam.
