All of these bugs are in the NEW or REOPENED state, and have not been
touched in 7 days or more.
You need to take a look at them, and decide on an initial action.
Generally, this means one of three things:
(1) You decide this bug is really quick to deal with (like, it's INVALID),
and so you get rid of it immediately.
(2) You decide the bug doesn't belong to you, and you reassign it to
someone else. (Hint: if you don't know who to reassign it to, make
sure that the Component field seems reasonable, and then use the
"Reset Assignee to default" option.)
(3) You decide the bug belongs to you, but you can't solve it this moment.
Accept the bug by setting the status to ASSIGNED.
