Bugs show up twice

[bbordwell]

When using this link:

https://launchpad.net/ubuntu/+bugs?field.searchtext=&orderby=-datecreated&field.status%3Alist=New&field.importance%3Alist=Undecided&assignee_option=none&field.assignee=&field.owner=&field.component=1&field.component=2&field.component-empty-marker=1&field.omit_dupes.used=&field.omit_dupes=on&field.has_patch.used=&field.has_no_package.used=&search=Search

alot of the bugs reported in the last day or two show up twice for no reason.
