Thanks for testing.

It means that Apache calls trac to process the error pages but trac 
and/or mod_python seems to think it's a normal request.

There may be a bug in mod_python or trac somewhere (I am not sure). 
But in any case it is obviously not a good idea to enable the 
localized error pages by default. I will disable them again with the 
next upload in Debian unstable and add the <Location /error/> thing as 
workaround to the documentation.

For you it is probably best to disable the stuff in 
/etc/apache2/conf.d/localized-error-pages, too. When I have a patch I 
will probably file a bug on Ubuntu, but I have no idea if or when it 
will be changed there. The problem was introduced in 2.2.12-1 and  
therefore only affects Karmic and Lucid.

Cheers,
