tomcat stopped working :(

I had everything working fine on my PC, which is a Suse10 box running Apache2 and Tomcat5.

I don't remember changing anything, but my webserver stopped working - I'm pretty sure Apache is working fine, but Tomcat isn't.  I can't access it either through Apache (mod_jk) or directly on port 8080.  Have a look yourself: http://malydog.homeip.net

I found this error in /var/log/tomcat5/base/catalina_log.2006-06-18.txt

javax.naming.NamingException: /srv/www/tomcat5/base/conf/tomcat-users.xml.new (Permission denied)

Considering the hell I went through setting this all up in the first place, I'm not even going to begin trying to sort it out myself.  HELP!

Here is the contents of the directory which contains tomcat-users.xml:
