Bugzilla: Bug Closed - Duplicate
When a Bug describes a problem already described by another Bug, it is closed as a DUPLICATE and a reference is made to the other Bug.
If your Bug is closed as a duplicate, and you believe this to be in error (do read the referred Bug description!), add information in the Bug describing why you think it is a different problem, and then reopen the Bug.
