Debug mode in Eclipse impossible?

I setup Eclipse to run openerp. With 5.06, I had no problem to run Openerp with run or debug option.
With 5.11, I can run openerp 5.11 in Eclipse and it runs fine but I cannot run in debug mode.
I get the following output
pydev debugger: starting
[2010-06-24 13:51:06,618] INFO:server:version - 5.0.11

[2010-06-24 13:51:07,164] INFO:web-services:the server is running, waiting for connections...

And when I try to connect through openerp-client, the client says "couldnot connect to server" and I get the following output:

/usr/local/lib/python2.6/dist-packages/openerp-server/tools/misc.py:750: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
  if hasattr(e, 'message'):
/usr/local/lib/python2.6/dist-packages/openerp-server/tools/misc.py:751: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
  return ustr(e.message)

Is there specific setup to do for openerp 5.11 in Eclipse?
Thanks
