User with right "Issues created by or assigned to the user" can't see issues assigned them
In Redmine 1.2.1 dev, there are issues visibility setting in "Administration" -> "Roles and permissions" with three options.
All non private issues
Issues created by or assigned to the user
Assume in a project we create a new role as "External users" and grant this role the issues visibility as "Issues created by or assigned to the user".
The "external" user can't see issue assigned him but he's able to access it.
Defect#9199 is very similar issue but not the same
