Currently Bugzilla is happy to accept invalid and/or mistyped components in the "Component Text" on the query page. If would be nice if it gave an error message instead or just giving an empty or an incomplete bug list.
Red Hat's current Bugzilla version is 2.18. I am moving all older open bugs to this version. Any bugs against the older versions will need to be verified that they are still bugs. This will help me also to sort them better.
No longer using the component text field.
