Track does not allow me to post comments on tickets

I have found a bug that was previously reported in ticket 13743 [1]. 
I want to confirm that bug and add the message that the browser show
when trying to login with OpenID. However, the tack system does not
allow me to post my comment. It show the next messages:


Warning: 
      * The action "untriaged" is not available.
      * No permissions to add a comment.

Trac detected an internal error: 
    TypeError: int() argument must be a string or a number,
    not 'NoneType'

I would be happy if I could post bugs and comments to the issue
system used in Plone.

A remember a discussion about the bug tracking system that would be
used by the Plone community [2]. However, I'm not sure about if
there is an agreement on the place where posting bugs. Currently in
Plone.org is recommended to use trac to report bugs [3].

Regards,
Daniel
