Error while parsing the account details

Hi trouble shooters,
I think I am facing a serious problem, when I try to create an account in Google Talk I am facing an error message. This error blocks me from proceeding further in creating an account. At work they need this account so please help me to create an account. I tried million times by restarting the system and recreating but no luck. Please help.

There was an error while parsing the account details.
The error message was: org.freedesktop.DBus.GLib.UnmappedError.McdAccountManagerError.Code0:
Failed to set parameter: Not all parameters were recognized
You can either go back and try to enter your
accounts’ details again or quit this assistant and
add accounts later from the Edit menu.
