[GeoNetwork-users] Problem with Dublin Core

Hi All!

I've tried new release 2.1 and I have this problem.
When I'm trying to create new Dublin Core metadata, GeoNetwork says
something like that: "Operation could not be performed",
and message appears in the log file:
"2007-10-07 16:39:41,296 ERROR [jeeves.service] - Exception when executing

I have no idea about this problem. I need to fix it up as soon as possible.
Please help me, I'll really appreciate it.
