Ok i have solved the issue... i downloaded the source code and found an exception in this line:
SPUser task_owner = properties.Web.EnsureUser(item["task_owner"].ToString());
the exception says that the user couldn't be found because the string item["task_owner"].ToString() got returned with some characters before the user name.

So i replace this line with this:
string user = item["task_owner"].ToString();
SPFieldLookupValue Userlookup = new SPFieldLookupValue(user);
SPUser task_owner = properties.Web.EnsureUser(Userlookup.LookupValue);
to clear up the returned string before ensure user search for the SPUser

Thank you very much
