Hello,

I have been receiving reports of error which I cannot interprete. So far 
it seems to be related to an old page cached, but I have been unable to 
move from that.

Please find the report below (Sakai 2.4.x on Tomcat 5.0 and Java 1.5). 
Any suggestions would be very welcome.

Regards,
Rafael
